      <Description>&lt;VulnDiscussion&gt;This policy setting controls whether Office 365 ProPlus applications notify users when potentially unsafe features or content are detected, or whether such features or content are silently disabled without notification. The Message Bar in Office 2016 applications is used to identify security issues, such as unsigned macros or potentially unsafe add-ins. When such issues are detected, the application disables the unsafe feature or content and displays the Message Bar at the top of the active window. The Message Bar informs the users about the nature of the security issue and, in some cases, provides the users with an option to enable the potentially unsafe feature or content, which could harm the user's computer.
 
If you enable this policy setting, Office 365 ProPlus applications do not display information in the Message Bar about potentially unsafe content that has been detected or has automatically been blocked.
 
If you disable this policy setting, Office 365 ProPlus applications display information in the Message Bar about content that has automatically been blocked.
 
If you do not configure this policy setting, if an Office 365 ProPlus application detects a security issue, the Message Bar is displayed.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls how the specified applications warn users when Visual Basic for Applications (VBA) macros are present.
 
If you enable this policy setting, you can choose from four options for determining how the specified applications will warn the user about macros:
 
- Disable all with notification: The application displays the Trust Bar for all macros, whether signed or unsigned. This option enforces the default configuration in Office.
- Disable all except digitally signed macros: The application displays the Trust Bar for digitally signed macros, allowing users to enable them or leave them disabled. Any unsigned macros are disabled, and users are not notified.
- Disable all without notification: The application disables all macros, whether signed or unsigned, and does not notify users.
- Enable all macros (not recommended): All macros are enabled, whether signed or unsigned. This option can significantly reduce security by allowing dangerous code to run undetected.
 
If you disable this policy setting, "Disable all with notification" will be the default setting.
 
If you do not configure this policy setting, when users open files in the specified applications that contain VBA macros, the applications open the files with the macros disabled and display the Trust Bar with a warning that macros are present and have been disabled. Users can inspect and edit the files if appropriate, but cannot use any disabled functionality until they enable it by clicking "Enable Content" on the Trust Bar. If the user clicks "Enable Content", then the document is added as a trusted document.
 
Important: If "Disable all except digitally signed macros" is selected, users will not be able to open unsigned Access databases.
 
Also, note that Microsoft Office stores certificates for trusted publishers in the Internet Explorer trusted publisher store. Earlier versions of Microsoft Office stored trusted publisher certificate information (specifically, the certificate thumbprint) in a special Office trusted publisher store. Microsoft Office still reads trusted publisher certificate information from the Office trusted publisher store, but it does not write information to this store.
 
Therefore, if you created a list of trusted publishers in a previous version of Microsoft Office and you upgrade to Office, your trusted publisher list will still be recognized. However, any trusted publisher certificates that you add to the list will be stored in the Internet Explorer trusted publisher store.&lt;/VulnDiscussion&gt;&lt;FalsePositives&gt;&lt;/FalsePositives&gt;&lt;FalseNegatives&gt;&lt;/FalseNegatives&gt;&lt;Documentable&gt;false&lt;/Documentable&gt;&lt;Mitigations&gt;&lt;/Mitigations&gt;&lt;SeverityOverrideGuidance&gt;&lt;/SeverityOverrideGuidance&gt;&lt;PotentialImpacts&gt;&lt;/PotentialImpacts&gt;&lt;ThirdPartyTools&gt;&lt;/ThirdPartyTools&gt;&lt;MitigationControl&gt;&lt;/MitigationControl&gt;&lt;Responsibility&gt;&lt;/Responsibility&gt;&lt;IAControls&gt;&lt;/IAControls&gt;</Description>

      <Description>&lt;VulnDiscussion&gt;This policy setting controls whether trusted locations on the network can be used.
  
If you enable this policy setting, users can specify trusted locations on network shares or in other remote locations that are not under their direct control by selecting the "Allow Trusted Locations on my network (not recommended)" check box in the Trusted Locations section of the Trust Center. Content, code, and add-ins are allowed to load from trusted locations with minimal security and without prompting the user for permission.
 
If you disable or do not configure this policy setting, the selected application ignores any network locations listed in the Trusted Locations section of the Trust Center. Disabling this policy setting does not delete any network locations from the Trusted Locations list. Instead, it forces the selected application to treat the locations as non-trusted and prevents users from adding new network locations to the list.
 
If you also deploy Trusted Locations via Group Policy, you should verify whether any of them are remote locations. If any of them are remote locations and you do not allow remote locations via this policy setting, those policy keys that point to remote locations will be ignored on client computers.
 
Disabling this policy setting will cause disruption for users who add network locations to the Trusted Locations list.

      <Description>&lt;VulnDiscussion&gt;This policy setting specifies the Microsoft ActiveX initialization security level for all Microsoft Office applications. ActiveX controls can adversely affect a computer directly. In addition, malicious code can be used to compromise an ActiveX control and attack a computer.
 
To indicate the safety of an ActiveX control, developers can denote them as Safe for Initialization (SFI). SFI indicates that a control is safe to open and run, and that it is not capable of causing a problem for any computer, regardless of whether it has persisted data values or not. If a control is not marked SFI, it is possible that the control could adversely affect a computer--or it could mean that the developers did not test the control in all situations and are not sure whether it might be compromised in the future. If you enable this policy setting, you can set the ActiveX security level to a number between 1 and 6. These security levels are as follows:
  
1. Regardless of how the control is marked, load it and use the persisted values (if any). This setting does not prompt the user.
 
2. If SFI, load the control in safe mode and use persisted values (if any). If not SFI, load in unsafe mode with persisted values (if any), or use the default (first-time initialization) settings. This level is similar to the default configuration, but does not prompt the user.
 
3. If SFI, load the control in unsafe mode and use persisted values (if any). If not SFI, prompt the user and advise them that it is marked unsafe. If the user chooses No at the prompt, do not load the control. Otherwise, load it with default (first-time initialization) settings.
 
4. If SFI, load the control in safe mode and use persisted values (if any). If not SFI, prompt the user and advise them that it is marked unsafe. If the user chooses No at the prompt, do not load the control. Otherwise, load it with default (first-time initialization) settings.
 
5. If SFI, load the control in unsafe mode and use persisted values (if any). If not SFI, prompt the user and advise them that it is marked unsafe. If the user chooses No at the prompt, do not load the control. Otherwise, load it with persisted values.
 
6. If SFI, load the control in safe mode and use persisted values (if any). If not SFI, prompt the user and advise them that it is marked unsafe. If the user chooses No at the prompt, do not load the control. Otherwise, load it with persisted values.
 
If you disable or do not configure this policy setting, if a control is marked SFI, the application loads the control in safe mode and uses persisted values (if any). If the control is not marked SFI, the application loads the control in unsafe mode with persisted values (if any), or uses the default (first-time initialization) settings. In both situations, the Message Bar informs users that the controls have been disabled and prompts them to respond.
 
Important: Some ActiveX controls do not respect the safe mode registry setting, and therefore might load persisted data even though you configure this setting to instruct the control to use safe mode. This setting only increases security for ActiveX controls that are accurately marked as SFI. In situations that involve malicious or poorly designed code, an ActiveX control might be inaccurately marked as SFI.&lt;/VulnDiscussion&gt;&lt;FalsePositives&gt;&lt;/FalsePositives&gt;&lt;FalseNegatives&gt;&lt;/FalseNegatives&gt;&lt;Documentable&gt;false&lt;/Documentable&gt;&lt;Mitigations&gt;&lt;/Mitigations&gt;&lt;SeverityOverrideGuidance&gt;&lt;/SeverityOverrideGuidance&gt;&lt;PotentialImpacts&gt;&lt;/PotentialImpacts&gt;&lt;ThirdPartyTools&gt;&lt;/ThirdPartyTools&gt;&lt;MitigationControl&gt;&lt;/MitigationControl&gt;&lt;Responsibility&gt;&lt;/Responsibility&gt;&lt;IAControls&gt;&lt;/IAControls&gt;</Description>

The Message Bar informs the users about the nature of the security issue and, in some cases, provides the users with an option to enable the potentially unsafe feature or content, which could harm the user's computer.
 
If you enable this policy setting, Office 365 ProPlus applications do not display information in the Message Bar about potentially unsafe content that has been detected or has automatically been blocked.&lt;/VulnDiscussion&gt;&lt;FalsePositives&gt;&lt;/FalsePositives&gt;&lt;FalseNegatives&gt;&lt;/FalseNegatives&gt;&lt;Documentable&gt;false&lt;/Documentable&gt;&lt;Mitigations&gt;&lt;/Mitigations&gt;&lt;SeverityOverrideGuidance&gt;&lt;/SeverityOverrideGuidance&gt;&lt;PotentialImpacts&gt;&lt;/PotentialImpacts&gt;&lt;ThirdPartyTools&gt;&lt;/ThirdPartyTools&gt;&lt;MitigationControl&gt;&lt;/MitigationControl&gt;&lt;Responsibility&gt;&lt;/Responsibility&gt;&lt;IAControls&gt;&lt;/IAControls&gt;</Description>

      <Description>&lt;VulnDiscussion&gt;This policy setting allows you to control how ActiveX controls in UserForms should be initialized based upon whether they are Safe for Initialization (SFI) or Unsafe for Initialization (UFI).
  
ActiveX controls are Component Object Model (COM) objects and have unrestricted access to users' computers. ActiveX controls can access the local file system and change the registry settings of the operating system. If a malicious user repurposes an ActiveX control to take over a user's computer, the effect could be significant. To help improve security, ActiveX developers can mark controls as SFI, which means that the developer states that the controls are safe to open and run and not capable of causing harm to any computers. If a control is not marked SFI, the control could adversely affect a computer, or the developers may not have tested the control in all situations and are not sure whether their control might be compromised at some future date. SFI controls run in safe mode, which limits their access to the computer. For example, a worksheet control can both read and write files when it is in unsafe mode, but perhaps only read from files when it is in safe mode. This functionality allows the control to be used in very powerful ways when safety was not important, but the control would still be safe for use in a Web page. If a control is not marked as SFI, it is marked UFI, which means that it is capable of affecting a user's computer. If UFI ActiveX controls are loaded, they are always loaded in unsafe mode.
  
If you enable this policy setting, you can choose from four options for loading controls in UserForms:
  
1. For a UFI or SFI signed control that supports safe and unsafe mode, load the control in unsafe mode. For an SFI signed control that only supports a safe mode configuration, load the control in safe mode. This option enforces the default configuration.
  
2. Users are prompted to determine how UserForm forms will load. The prompt only displays once per session within an application. When users respond to the prompt, loading continues based on whether the control is UFI or SFI:
  
- For a UFI signed control, if users respond Yes to the prompt, load the control in unsafe mode. If users respond No, load the control using the default properties.
- For an SFI signed control that supports both safe and unsafe modes, if users respond Yes to the prompt, load the control in unsafe mode. If users respond No, load the control using safe mode. If the SFI control can only support safe mode, load the control in safe mode. This option is the default configuration in the Microsoft Office 365 ProPlus release.
  
3. Users are prompted to determine how UserForm forms will load. The prompt only displays once per session within an application. When users respond to the prompt, loading continues based on whether the control is UFI or SFI:
  
- For a UFI signed control, if users respond Yes to the prompt, load the control in unsafe mode. If users respond No, load the control with its default properties.
- For an SFI signed control, load in safe mode.
  
4. For a UFI signed control, load with the default properties of the control. For an SFI signed control, load in safe mode (considered to be the safest mode).

If you enable this policy setting, you can choose from three options to control whether and how Flash is blocked from activation:
 
1. "Block all activation" prevents the Flash control from being loaded, whether directly referenced by the document or indirectly by another embedded object.

3. "Allow all activation" restores Office's default behavior, allowing the Flash control to be activated.
 
Because this setting is not a true Group Policy setting and "tattoos" the registry, enabling the "Allow all activation" option is the only way to restore default behavior after either of the "Block" options has been applied.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls whether trusted locations on the network can be used.
 
If you enable this policy setting, users can specify trusted locations on network shares or in other remote locations that are not under their direct control by selecting the "Allow Trusted Locations on my network (not recommended)" check box in the Trusted Locations section of the Trust Center. Content, code, and add-ins are allowed to load from trusted locations with minimal security and without prompting the user for permission.
 
If you disable or do not configure this policy setting, the selected application ignores any network locations listed in the Trusted Locations section of the Trust Center. Disabling this policy setting does not delete any network locations from the Trusted Locations list. Instead, it forces the selected application to treat the locations as non-trusted and prevents users from adding new network locations to the list.
 
If you also deploy Trusted Locations via Group Policy, you should verify whether any of them are remote locations. If any of them are remote locations and you do not allow remote locations via this policy setting, those policy keys that point to remote locations will be ignored on client computers.
 
Disabling this policy setting will cause disruption for users who add network locations to the Trusted Locations list. However, it is not recommended to enable this policy setting (as the "Allow Trusted Locations on my network (not recommended)" check box itself states), so in practice it should be possible to disable this policy setting in most situations without causing significant usability issues for most users.&lt;/VulnDiscussion&gt;&lt;FalsePositives&gt;&lt;/FalsePositives&gt;&lt;FalseNegatives&gt;&lt;/FalseNegatives&gt;&lt;Documentable&gt;false&lt;/Documentable&gt;&lt;Mitigations&gt;&lt;/Mitigations&gt;&lt;SeverityOverrideGuidance&gt;&lt;/SeverityOverrideGuidance&gt;&lt;PotentialImpacts&gt;&lt;/PotentialImpacts&gt;&lt;ThirdPartyTools&gt;&lt;/ThirdPartyTools&gt;&lt;MitigationControl&gt;&lt;/MitigationControl&gt;&lt;Responsibility&gt;&lt;/Responsibility&gt;&lt;IAControls&gt;&lt;/IAControls&gt;</Description>

If you enable this policy setting, DDE server lookup is not allowed, and users cannot turn on DDE server lookup in the Trust Center.
 
Note: If you are using Dynamic Data Exchange (DDE) server launch, which is not recommended, do not enable this policy setting, because DDE server launch requires DDE server lookup to be on.
 
If you disable or do not configure this policy setting, DDE server lookup is turned on, but users can turn off DDE server lookup in the Trust Center.
 
Note: This policy setting only applies to subscription versions of Office, such as Office 365 ProPlus.&lt;/VulnDiscussion&gt;&lt;FalsePositives&gt;&lt;/FalsePositives&gt;&lt;FalseNegatives&gt;&lt;/FalseNegatives&gt;&lt;Documentable&gt;false&lt;/Documentable&gt;&lt;Mitigations&gt;&lt;/Mitigations&gt;&lt;SeverityOverrideGuidance&gt;&lt;/SeverityOverrideGuidance&gt;&lt;PotentialImpacts&gt;&lt;/PotentialImpacts&gt;&lt;ThirdPartyTools&gt;&lt;/ThirdPartyTools&gt;&lt;MitigationControl&gt;&lt;/MitigationControl&gt;&lt;Responsibility&gt;&lt;/Responsibility&gt;&lt;IAControls&gt;&lt;/IAControls&gt;</Description>

- Allow different, but warn - Excel opens the files properly, but warns users about the file type mismatch. This option is the default configuration in Excel.
- Always match file type - Excel does not open any files that have non-matching extensions.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls how Excel will warn users when WEBSERVICE functions are present.
 
If you enable this policy setting, you can choose from three options for determining how the specified applications will warn the user about WEBSERVICE functions:
- Disable all with notification: The application displays the Trust Bar for all WEBSERVICE functions. This option enforces the default configuration in Office.
- Disable all without notification: The application disables all WEBSERVICE functions and does not notify users.
- Enable all WEBSERVICE functions (not recommended): The application enables all WEBSERVICE functions and does not notify users. This option can significantly reduce security by allowing information disclosure to third-party web services.
 
If you disable this policy setting, the “Disable all with notification” will be the default setting.
 
If you do not configure this policy setting, when users open workbooks that contain WEBSERVICE functions, Excel will open the files with the WEBSERVICE functions disabled and display the Trust Bar with a warning that WEBSERVICE functions are present and have been disabled. Users can inspect and edit the files if appropriate, but cannot use any disabled functionality until they enable it by clicking "Enable Content" on the Trust Bar.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls which authentication method Outlook uses to authenticate with Microsoft Exchange Server. Note: Exchange Server supports the Kerberos authentication protocol and NTLM for authentication. The Kerberos protocol is the more secure authentication method and is supported on Windows 2000 Server and later versions. NTLM authentication is supported in pre-Windows 2000 environments.
 
If you enable this policy setting, you can choose from three different options for controlling how Outlook authenticates with Microsoft Exchange Server:

- Kerberos password authentication. Outlook attempts to authenticate using the Kerberos protocol only.
- NTLM password authentication. Outlook attempts to authenticate using NTLM only.
 
If you disable or do not configure this policy setting, Outlook will attempt to authenticate using the Kerberos authentication protocol.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls how Outlook retrieves Certificate Revocation Lists to verify the validity of certificates. Certificate revocation lists (CRLs) are lists of digital certificates that have been revoked by their controlling certificate authorities (CAs), typically because the certificates were issued improperly or their associated private keys were compromised.
 
If you enable this policy setting, you can choose from three options to govern how Outlook uses CRLs:
- Use system Default. Outlook relies on the CRL download schedule that is configured for the operating system.
- When online always retrieve the CRL. This option is the default configuration in Outlook.
- Never retrieve the CRL. Outlook will not attempt to download the CRL for a certificate, even if it is online. This option can reduce security.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls which set of security settings are enforced in Outlook. If you enable this policy setting, you can choose from four options for enforcing Outlook security settings:
  
- Outlook Default Security - This option is the default configuration in Outlook. Users can configure security themselves, and Outlook ignores any security-related settings configured in Group Policy.
- Use Security Form from "Outlook Security Settings" Public Folder - Outlook uses the settings from the security form published in the designated public folder.
- Use Security Form from "Outlook 10 Security Settings" Public Folder - Outlook uses the settings from the security form published in the designated public folder.
- Use Outlook Security Group Policy - Outlook uses security settings from Group Policy. Important: You must enable this policy setting if you want to apply the other Outlook security policy settings mentioned in this guide. If you disable or do not configure this policy setting, Outlook users can configure security for themselves, and Outlook ignores any security-related settings that are configured in Group Policy.
 
Note: In previous versions of Outlook, when security settings were published in a form in Exchange Server public folders, users who needed these settings required the HKEY_CURRENT_USER &gt;&gt; Software &gt;&gt; Policies &gt;&gt; Microsoft &gt;&gt; Security &gt;&gt; CheckAdminSettings registry key to be set on their computers for the settings to apply. In Outlook, the CheckAdminSettings registry key is no longer used to determine users' security settings. Instead, the Outlook Security Mode setting can be used to determine whether Outlook security should be controlled directly by Group Policy, by the security form from the Outlook Security Settings Public Folder, or by the settings on users' own computers.&lt;/VulnDiscussion&gt;&lt;FalsePositives&gt;&lt;/FalsePositives&gt;&lt;FalseNegatives&gt;&lt;/FalseNegatives&gt;&lt;Documentable&gt;false&lt;/Documentable&gt;&lt;Mitigations&gt;&lt;/Mitigations&gt;&lt;SeverityOverrideGuidance&gt;&lt;/SeverityOverrideGuidance&gt;&lt;PotentialImpacts&gt;&lt;/PotentialImpacts&gt;&lt;ThirdPartyTools&gt;&lt;/ThirdPartyTools&gt;&lt;MitigationControl&gt;&lt;/MitigationControl&gt;&lt;Responsibility&gt;&lt;/Responsibility&gt;&lt;IAControls&gt;&lt;/IAControls&gt;</Description>

- Prompt user. The user will be prompted to approve every access attempt.
- Automatically approve. Outlook will automatically grant programmatic access requests from any program. This option can create a significant vulnerability, and is not recommended.
- Automatically deny. Outlook will automatically deny programmatic access requests from any program.
- Prompt user based on computer security. Outlook will only prompt users when antivirus software is out of date or not running. This is the default configuration.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls the security level for macros in Outlook.
 
If you enable this policy setting, you can choose from four options for handling macros in Outlook:
- Always warn. This option corresponds to the "Warnings for all macros" option in the "Macro Security" section of the Outlook Trust Center. Outlook disables all macros that are not opened from a trusted location, even if the macros are signed by a trusted publisher. For each disabled macro, Outlook displays a security alert dialog box with information about the macro and its digital signature (if present), and allows users to enable the macro or leave it disabled.
- Never warn, disable all. This option corresponds to the "No warnings and disable all macros" option in the Trust Center. Outlook disables all macros that are not opened from trusted locations, and does not notify users.
- Warning for signed, disable unsigned. This option corresponds to the "Warnings for signed macros; all unsigned macros are disabled" option in the Trust Center. Outlook handles macros as follows:
--If a macro is digitally signed by a trusted publisher, the macro can run if the user has already trusted the publisher.
--If a macro has a valid signature from a publisher that the user has not trusted, the security alert dialog box for the macro lets the user choose whether to enable the macro for the current session, disable the macro for the current session, or to add the publisher to the Trusted Publishers list so that it will run without prompting the user in the future.
--If a macro does not have a valid signature, Outlook disables it without prompting the user, unless it is opened from a trusted location.
This option is the default configuration in Outlook.
- No security check. This option corresponds to the "No security check for macros (Not recommended)" option in the Trust Center. Outlook runs all macros without prompting users. This configuration makes users' computers vulnerable to potentially malicious code and is not recommended.
 
If you disable or do not configure this policy setting, the behavior is the equivalent of Enabled -- Warning for signed, disable unsigned.&lt;/VulnDiscussion&gt;&lt;FalsePositives&gt;&lt;/FalsePositives&gt;&lt;FalseNegatives&gt;&lt;/FalseNegatives&gt;&lt;Documentable&gt;false&lt;/Documentable&gt;&lt;Mitigations&gt;&lt;/Mitigations&gt;&lt;SeverityOverrideGuidance&gt;&lt;/SeverityOverrideGuidance&gt;&lt;PotentialImpacts&gt;&lt;/PotentialImpacts&gt;&lt;ThirdPartyTools&gt;&lt;/ThirdPartyTools&gt;&lt;MitigationControl&gt;&lt;/MitigationControl&gt;&lt;Responsibility&gt;&lt;/Responsibility&gt;&lt;IAControls&gt;&lt;/IAControls&gt;</Description>

      <Description>&lt;VulnDiscussion&gt;This policy setting controls whether trusted locations on the network can be used.
 
If you enable this policy setting, users can specify trusted locations on network shares or in other remote locations that are not under their direct control by clicking the "Add new location" button in the Trusted Locations section of the Trust Center. Content, code, and add-ins are allowed to load from trusted locations with minimal security and without prompting the user for permission.
 
If you disable this policy setting, the selected application ignores any network locations listed in the Trusted Locations section of the Trust Center.
 
If you also deploy Trusted Locations via Group Policy, you should verify whether any of them are remote locations. If any of them are remote locations and you do not allow remote locations via this policy setting, those policy keys that point to remote locations will be ignored on client computers.
 
Disabling this policy setting does not delete any network locations from the Trusted Locations list, but causes disruption for users who add network locations to the Trusted Locations list. Users are also prevented from adding new network locations to the Trusted Locations list in the Trust Center. We recommended that you do not enable this policy setting as the "Allow Trusted Locations on my network (not recommended)" check box also states. Therefore, in practice, it should be possible to disable this policy setting in most situations without causing significant usability issues for most users.

If you enable this policy setting, you can choose from four options for determining how the specified applications will warn the user about macros:
 
- Disable all with notification: The application displays the Trust Bar for all macros, whether signed or unsigned. This option enforces the default configuration in Office.
- Disable all except digitally signed macros: The application displays the Trust Bar for digitally signed macros, allowing users to enable them or leave them disabled. Any unsigned macros are disabled, and users are not notified.
- Disable all without notification: The application disables all macros, whether signed or unsigned, and does not notify users.
- Enable all macros (not recommended): All macros are enabled, whether signed or unsigned. This option can significantly reduce security by allowing dangerous code to run undetected.
 
If you disable this policy setting, "Disable all with notification" will be the default setting.
 
If you do not configure this policy setting, when users open files in the specified applications that contain VBA macros, the applications open the files with the macros disabled and display the Trust Bar with a warning that macros are present and have been disabled. Users can inspect and edit the files if appropriate, but cannot use any disabled functionality until they enable it by clicking "Enable Content" on the Trust Bar. If the user clicks "Enable Content", then the document is added as a trusted document.
 
Important: If "Disable all except digitally signed macros" is selected, users will not be able to open unsigned Access databases.
 
Also, note that Microsoft Office stores certificates for trusted publishers in the Internet Explorer trusted publisher store. Earlier versions of Microsoft Office stored trusted publisher certificate information (specifically, the certificate thumbprint) in a special Office trusted publisher store. Microsoft Office still reads trusted publisher certificate information from the Office trusted publisher store, but it does not write information to this store.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls how the specified applications warn users when Visual Basic for Applications (VBA) macros are present.
 
If you enable this policy setting, you can choose from four options for determining how the specified applications will warn the user about macros:
  
- Disable all with notification: The application displays the Trust Bar for all macros, whether signed or unsigned. This option enforces the default configuration in Office.
- Disable all except digitally signed macros: The application displays the Trust Bar for digitally signed macros, allowing users to enable them or leave them disabled. Any unsigned macros are disabled, and users are not notified.
- Disable all without notification: The application disables all macros, whether signed or unsigned, and does not notify users.
- Enable all macros (not recommended): All macros are enabled, whether signed or unsigned. This option can significantly reduce security by allowing dangerous code to run undetected.
  
If you disable this policy setting, "Disable all with notification" will be the default setting.
  
If you do not configure this policy setting, when users open files in the specified applications that contain VBA macros, the applications open the files with the macros disabled and display the Trust Bar with a warning that macros are present and have been disabled. Users can inspect and edit the files if appropriate, but cannot use any disabled functionality until they enable it by clicking "Enable Content" on the Trust Bar. If the user clicks "Enable Content", then the document is added as a trusted document.
  
Important: If "Disable all except digitally signed macros" is selected, users will not be able to open unsigned Access databases.
  
Also, note that Microsoft Office stores certificates for trusted publishers in the Internet Explorer trusted publisher store. Earlier versions of Microsoft Office stored trusted publisher certificate information (specifically, the certificate thumbprint) in a special Office trusted publisher store. Microsoft Office still reads trusted publisher certificate information from the Office trusted publisher store, but it does not write information to this store.
  
Therefore, if you created a list of trusted publishers in a previous version of Microsoft Office and you upgrade to Office, your trusted publisher list will still be recognized.

      <Description>&lt;VulnDiscussion&gt;This policy setting controls whether trusted locations on the network can be used.
 
If you enable this policy setting, users can specify trusted locations on network shares or in other remote locations that are not under their direct control by clicking the "Add new location" button in the Trusted Locations section of the Trust Center. Content, code, and add-ins are allowed to load from trusted locations with minimal security and without prompting the user for permission.
 
If you disable this policy setting, the selected application ignores any network locations listed in the Trusted Locations section of the Trust Center.
 
If you also deploy Trusted Locations via Group Policy, you should verify whether any of them are remote locations. If any of them are remote locations and you do not allow remote locations via this policy setting, those policy keys that point to remote locations will be ignored on client computers.
 
Disabling this policy setting does not delete any network locations from the Trusted Locations list, but causes disruption for users who add network locations to the Trusted Locations list. Users are also prevented from adding new network locations to the Trusted Locations list in the Trust Center. We recommended that you do not enable this policy setting as the "Allow Trusted Locations on my network (not recommended)" check box also states. Therefore, in practice, it should be possible to disable this policy setting in most situations without causing significant usability issues for most users.
