.SYNOPSIS This function enables the administrator to create the hybrid mail flow objects post migration. .DESCRIPTION This function enables the administrator to create the hybrid mail flow objects post migration. .PARAMETER GROUPSMTPADDRESS *REQUIRED* This attribute specifies the windows mail address of the group to be migrated. .PARAMETER GLOBALCATALOGSERVER *REQUIRED* This attribute specifies the global catalog server that will be utilized to process Active Directory commands. .PARAMETER ACIVEDIRECTORYCREDENTIAL *REQUIRED* This attribute specifies the credentials for Active Directory connections. Domain admin credentials are required if the group does not have resorces outside of the domain where the group resides. Enterprise admin credentials are required if the group has resources across multiple domains in the forest. .PARAMETER EXCHANGESERVER *OPTIONAL* *REQUIRED with enableHybridMailFlow:TRUE* This parameter specifies that local Exchange on premises installation utilized for hybrid mail flow enablement. Exchange server is no required for migrations unlss enable hyrbid mail flow is required. .PARAMETER EXCHANGECREDENTIAL *OPTIONAL* *REQUIRED with ExchangeServer specified* This is the credential utilized to connect to the Exchange server remote powershell instance. Exchange Organization Adminitrator rights are recommended. .PARAMETER EXCHANGEAUTHENTICATIONMETHOD *OPTIONAL* *DEFAULT: BASIC* This specifies the authentication method for the Exchage on-premsies remote powershell session. .PARAMETER EXCHANGEONLINECREDENTIAL *REQUIRED if ExchangeOnlineCertificateThumbprint not specified* *NOT ALLOWED if ExchangeCertificateThubprint is specified* The credential utilized to connect to Exchange Online. This account cannot have interactive logon requirements such as multi-factored authentication. Exchange Organization Administrator rights recommened. .PARAMETER EXCHANGEONLINECERTIFICATETHUMBPRINT *REQUIRED if ExchangeOnlineCredential is not specified* *NOT ALLOWED if ExchangeCredential is specified* This is the thumbprint of the certificate utilized to authenticate to the Azure application created for Exchange Certificate Authentication .PARAMETER EXCHANGEONLINEORGANIZATIONNAME *REQUIRED only with ExchangeCertificateThumbpint* This specifies the Exchange Online oragnization name in domain.onmicroosft.com format. .PARAMETER EXCHANGEONLINEENVIRONMENTNAME *OPTIONAL* *DEFAULT: O365DEFAULT This specifies the Exchange Online environment to connect to if a non-commercial forest is utilized. .PARAMETER EXCHANGEONLINEAPPID *REQUIRED with ExchangeCertificateThumbprint* This specifies the application ID of the Azure application for Exchange certificate authentication. .PARAMETER LOGFOLDERPATH *REQUIRED* This is the logging directory for storing the migration log and all backup XML files. If running multiple SINGLE instance migrations use different logging directories. .OUTPUTS None .EXAMPLE enable-HybridMailFlow -groupSMTPAddress SMTPAddress -globalCatalogServer GC.domain.com -activeDirectoryCredential $cred -exchangeServer server.domain.com -exchangeServerCredential $cred -exchangeOnlineCredential $cred #> Function enable-hybridMailFlowPostMigration { [cmdletbinding()] Param ( [Parameter(Mandatory = $true)] [string]$groupSMTPAddress, #Local Active Director Domain Controller Parameters [Parameter(Mandatory = $true)] [string]$globalCatalogServer, [Parameter(Mandatory = $true)] [pscredential]$activeDirectoryCredential, #Exchange On-Premises Parameters [Parameter(Mandatory = $false)] [string]$exchangeServer=$NULL, [Parameter(Mandatory = $false)] [pscredential]$exchangeCredential=$NULL, [Parameter(Mandatory = $false)] [ValidateSet("Basic","Kerberos")] [string]$exchangeAuthenticationMethod="Basic", #Exchange Online Parameters [Parameter(Mandatory = $false)] [pscredential]$exchangeOnlineCredential=$NULL, [Parameter(Mandatory = $false)] [string]$exchangeOnlineCertificateThumbPrint="", [Parameter(Mandatory = $false)] [string]$exchangeOnlineOrganizationName="", [Parameter(Mandatory = $false)] [ValidateSet("O365Default","O365GermanyCloud","O365China","O365USGovGCCHigh","O365USGovDoD")] [string]$exchangeOnlineEnvironmentName="O365Default", [Parameter(Mandatory = $false)] [string]$exchangeOnlineAppID="", #Define other mandatory parameters [Parameter(Mandatory = $true)] [string]$logFolderPath, [Parameter(Mandatory = $true)] [string]$OU = "NotSet" ) #Declare function variables. $global:logFile=$NULL #This is the global variable for the calculated log file name [string]$global:staticFolderName="\DLMigration\" $coreVariables = @{ useOnPremisesExchange = @{ "Value" = $FALSE ; "Description" = "Boolean determines if Exchange on premises should be utilized" } exchangeOnPremisesPowershellSessionName = @{ "Value" = "ExchangeOnPremises" ; "Description" = "Static exchange on premises powershell session name" } exchangeOnlinePowershellModuleName = @{ "Value" = "ExchangeOnlineManagement" ; "Description" = "Static Exchange Online powershell module name" } activeDirectoryPowershellModuleName = @{ "Value" = "ActiveDirectory" ; "Description" = "Static active directory powershell module name" } dlConversionPowershellModule = @{ "Value" = "DLConversionV2" ; "Description" = "Static dlConversionv2 powershell module name" } globalCatalogPort = @{ "Value" = ":3268" ; "Description" = "Global catalog port definition" } globalCatalogWithPort = @{ "Value" = ($globalCatalogServer+($corevariables.globalCatalogPort.value)) ; "Description" = "Global catalog server with port" } } #Static variables utilized for the Exchange On-Premsies Powershell. $onPremExchangePowershell = @{ exchangeServerConfiguration = @{"Value" = "Microsoft.Exchange" ; "Description" = "Defines the Exchange Remote Powershell configuration"} exchangeServerAllowRedirection = @{"Value" = $TRUE ; "Description" = "Defines the Exchange Remote Powershell redirection preference"} exchangeServerURI = @{"Value" = "https://"+$exchangeServer+"/powershell" ; "Description" = "Defines the Exchange Remote Powershell connection URL"} exchangeServerURIKerberos = @{"Value" = "http://"+$exchangeServer+"/powershell" ; "Description" = "Defines the Exchange Remote Powershell connection URL"} exchangeOnPremisesPowershellSessionName = @{ "Value" = "ExchangePowershell" ; "Description" = "Exchange On-Premises powershell session name."} } #Declare logging variables. $xmlFiles = @{ office365DLConfigurationXML = @{ "Value" = "office365DLConfigurationXML" ; "Description" = "XML file that exports the Office 365 DL configuration"} routingContactXML= @{ "Value" = "routingContactXML" ; "Description" = "XML file holds the routing contact configuration when intially created"} routingDynamicGroupXML= @{ "Value" = "routingDynamicGroupXML" ; "Description" = "XML file holds the routing contact configuration when mail enabled"} } $routingContactConfig=$NULL $routingDynamicGroup=$NULL $office365DLConfiguration = $NULL #Create the log file. new-LogFile -groupSMTPAddress $groupSMTPAddress.trim() -logFolderPath $logFolderPath write-functionParameters -keyArray $MyInvocation.MyCommand.Parameters.Keys -parameterArray $PSBoundParameters -variableArray (Get-Variable -Scope Local -ErrorAction Ignore) write-hashTable -hashTable $xmlFiles write-hashTable -hashTable $onPremExchangePowershell write-hashTable -hashTable $coreVariables #Start function processing.
