        .SYNOPSIS
            The Office 365 Recommended Configuration Analyzer (ORCA)
 
        .DESCRIPTION
            Office 365 Recommended Configuration Analyzer (ORCA)
 
            The Get-ORCAReport command generates a HTML report based on the Office 365 ATP recommended practices article:
            https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/recommended-settings-for-eop-and-office365-atp

            - Bootstrap - MIT License https://getbootstrap.com/docs/4.0/about/license/
            - Fontawesome - CC BY 4.0 License - https://fontawesome.com/license/free
 
        .PARAMETER NoConnect
            Prevents ORCA from connecting automatically to Exchange Online. In most circumstances you will not want to do this, we will
            detect if you're connected or not connected as part of running ORCA. Connection will only occur if we detect you are not
            connected.
         
        .PARAMETER NoVersionCheck
            Prevents ORCA from determining if it's running the latest version. It's always very important to be running the latest
            version of ORCA. We will change guidelines as the product and the recommended practices article changes. Not running the
            latest version might provide recommendations that are no longer valid.
 
        .PARAMETER AlternateDNS
            Will perform DNS checks using an alternate DNS server. This is really important if your organisation uses split DNS. Checks
            for your DKIM deployment for instance might fail if your DNS resolver is resolving your domains to the internal zone. This is
            because your internal zone doesn't require to have the DKIM selector records published. In these instances use the AlternateDNS
            flag to use different resolvers (ones that will provide the external DNS records for your domains).
 
 
        .PARAMETER Collection
            Internal only.
 
        .EXAMPLE
            Get-ORCAReport

            Get-ORCAReport -AlternateDNS @("10.20.30.40","40.20.30.10")

        .SYNOPSIS
            The Office 365 Recommended Configuration Analyzer (ORCA)
 
        .DESCRIPTION
            Office 365 Recommended Configuration Analyzer (ORCA)
 
            Unless you are wanting to automate ORCA, do not use Invoke-ORCA, run Get-ORCAReport instead!!
 
            The Invoke-ORCA command allows you to output different formats based on the Office 365 ATP recommended practices article:
            https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/recommended-settings-for-eop-and-office365-atp
 
            HTML Output report uses open source components for HTML formatting:
            - Bootstrap - MIT License https://getbootstrap.com/docs/4.0/about/license/
            - Fontawesome - CC BY 4.0 License - https://fontawesome.com/license/free
 
        .PARAMETER Output
            Array of output modules you would like to invoke. You can specify multiple different outputs. Outputs are modular, and
            additional outputs can be written and placed in the modules Outputs directory if required.
 
            Out of the box, the following outputs are included
            - HTML
            - JSON (File)
            - Cosmos DB (Requires CosmosDB third-party module)
 
            As this is an array, you can specify different outputs
             
            -Output "HTML"
                Will output just HTML
            -Output @("HTML","JSON")
                Will output the HTML report and the JSON report
         
        .PARAMETER OutputOptions
            Array of options for the output modules.
 
            Example if running a Cosmos output, you'll need to tell it which account, database and key to use like this:
 
            -OutputOptions @{Cosmos=@{Account='MyCosmosAccount';Database='MyCosmosDB';Key='GFJqJesi2Rq910E0G7P4WoZkzowzbj23Sm9DUWFX0l0P8o16mYyuaZBN00Nbtj9F1QQnumzZKSGZwknXGERrlA==';Collection='MyORCA'}}
 
            If you're running multiple different outputs, just use a different key for that output module, for instance this will provide the Cosmos details to the Cosmos module
            and HTML details to the HTML module.
 
            -OutputOptions @{HTML=@{DisplayReport=$False};Cosmos=@{Account='MyCosmosAccount';Database='MyCosmosDB';Key='GFJqJesi2Rq910E0G7P4WoZkzowzbj23Sm9DUWFX0l0P8o16mYyuaZBN00Nbtj9F1QQnumzZKSGZwknXGERrlA==';Collection='MyORCA'}}
         
        .PARAMETER PerformVersionCheck
            Prevents ORCA from determining if it's running the latest version if set to $False. It's always very important to be running the latest
            version of ORCA. We will change guidelines as the product and the recommended practices article changes. Not running the
            latest version might provide recommendations that are no longer valid.
 
        .PARAMETER Connect
            Prevents ORCA from connecting automatically to Exchange Online if set to $False. In most circumstances you will not want to do this, we will
            detect if you're connected or not connected as part of running ORCA. Connection will only occur if we detect you are not
            connected.
 
        .PARAMETER AlternateDNS
            Will perform DNS checks using an alternate DNS server. This is really important if your organisation uses split DNS. Checks
            for your DKIM deployment for instance might fail if your DNS resolver is resolving your domains to the internal zone. This is
            because your internal zone doesn't require to have the DKIM selector records published. In these instances use the AlternateDNS
            flag to use different resolvers (ones that will provide the external DNS records for your domains).
 
        .PARAMETER InstallModules
            Attempts to install missing modules (such as Exchange Online Management) in to the CurrentUser scope if they are missing. Defaults to $True
 
        .PARAMETER Collection
            Internal only.
 
        .EXAMPLE
            Invoke-ORCA -Output "HTML"
 
        .EXAMPLE
            Invoke-ORCA -Output @("HTML","JSON")
 
        .EXAMPLE
            Invoke-ORCA -Output @("HTML","JSON") -OutputOptions @{HTML=@{DisplayReport=$False}}
