This script will capture all recipients in a source tenant and recreate them as contacts in a target tenant, excluding objects (by default) whose primary SMTP address matches an accepted domain in the target tenant. This script is useful in a divestiture scenario (where one environment is splitting into one or more separate environments) and there is a need to maintain replyability for objects that are cached in Outlook profiles. If you have the ability to configure Forefront Identity Manager or AADConnect to sync objects, it is preferred, as this is more of a "point in time" copy and does not support delta updates or deletions in the target environment, since it is not using the a sync API. While it doesn't support deltas, it will allow you to run it multiple times and overwrite existing objects in the target environment. .PARAMETER ConfirmDeletes Confirm deletes in target environment if ProcessDeletes switch is used. .PARAMETER ExcludedDomains List of primary SMTP domains. Objects whose PrimarySmtpAddress value matches any domain in this list will NOT be imported as a contact. .PARAMETER ExcludedObjects List of source objects (as email address) to exclude. By default, the DiscoverySearch mailbox is excluded. .PARAMETER ExportFile Specify a custom export file to save the GAL objects. .PARAMETER ExportOnly Create only an export file from the source environment. .PARAMETER InputFile Specify an input file to import a previously exported GALSync. .PARAMETER ProcessTargetDeletes Delete contact objects synced to target envrionment that do not appear in source environment. Must include ConfirmDeletes switch to actually process deletes. .PARAMETER RecipientTypes Specify types of recipients to include in export/import. .PARAMETER ResultSize Use this to export a fixed number of objects. Useful for testing the process on a small scale. Defaults to "Unlimited" if no value is specified. This parameter has no effect on imports. .PARAMETER SourceConnectionUri Set the source connection URI. .PARAMETER SourceCredential Source environment credentials. .PARAMETER SourceEnvironment Determines authentication scheme used. Select ExchangeOnline (default) for Basic or ExchangeOnPrem for Kerberos. .PARAMETER SyncAttribute Use this parameter to specify a custom attribute in which to store metadata or information about the synced object. For example, you may want to use this attribute to flag objects that were imported. .PARAMETER SyncAttributeValue Specify a value to place in the SyncAttribute. .PARAMETER TargetConnectionUri Set the target connection URI. .PARAMETER TargetCredential Target environment credential. .PARAMETER TargetEnvironment Determines authentication scheme used. Select ExchangeOnline (default) for Basic or ExchangeOnPrem for Kerberos. .EXAMPLE .\Copy-StaticGAL.ps1 -RecipientTypes UserMailbox,MailUser -ResultSize 2 Copy 2 UserMailbox and MailUser objects from source tenant to target tenant as contact objects and prompt for source/target credentials. .EXAMPLE .\Copy-StaticGAL.ps1 -RecipientTypes UserMailbox -ResultSize 2 -ExcludedObjects user1@fabrikam.com,user2@contoso.com Copy 2 UserMailbox objects from source tenant to target tenant contact objects, except user1@fabrikam.com and user2@contoso.com. .EXAMPLE .\Copy-StaticGAL.ps1 -InputFile GALExport.Csv -TargetConnectionUri 'https://ExchangeServer1/PowerShell/' TargetEnvironment ExchangeOnPrem Import the file GALExport.csv as contacts into the target on-premises environment via ExchangeServer1 with Kerberos authentication. .EXAMPLE .\Copy-StaticGAL.ps1 -ExportOnly Export a copy of the GAL to CSV from an Office 365 tenant and prompt for credentials. .EXAMPLE .\Copy-StaticGAL.ps1 -InputFile GALExport.csv -RecipientTypes MailUser -TargetCredential $TargetCred -SyncAttribute CustomAttribute15 -SyncAttributeValue StaticGAL Import MailUser objects from file GALExport.csv into target tenant using stored PSCredential object $TargetCred. Set CustomAttribute15 on target contact object to 'StaticGAL'. .EXAMPLE .\Copy-StaticGAL.ps1 -InputFile GALExport.csv -TargetCredential $TargetCred -SyncAttribute CustomAttribute15 -SyncAttributeValue StaticGAL -ProcessTargetDeletes -ConfirmDeletes Import objects from file GALExport.csv into target tenant using stored PSCredential object $TargetCred. Set CustomAttribute15 on target contact object to 'StaticGAL'. Delete objects in target environment with CustomAttribute15 set to 'StaticGAL' that are not present in the GALExport.csv input file. .LINK .NOTES $SourceCredential and $TargetCredential take standard PSCredential objects. It would be best to test by setting -ResultSize to a low integer and running several different RecipentTyes (default is all types) to ensure that the process is working correctly between your tenants and that the target objects look as anticipated. Revision List: 2022-01-24 : Published to PS Gallery. 2016-07-23 : Added delete functionality 2016-07-22 : Updated ExcludedDomains syntax to always exclude accepted domains in target environment.
