I'm working on a migration project where the company had previously set up a resource forest (ForestA) with Exchange 2007, and a User forest (ForestB) where all accounts are located. For reasons only known to the client they are wanting to revert back to a single forest (ForestB), will have Exchange 2010 installed.
I am testing doing a cross-forest mailbox move of the linked mailbox back to the account forest, but I am encountering and error that states.
Cannot find a recipient that has mailbox GUID '3493bb69-457d-4e5c-9584-7e0f6c210565'
The command I am using for the move is:
New-MoveRequest -Identity 'user16@FORESTA.com' -RemoteLegacy -RemoteTargetDatabase 'Mailbox Database' -RemoteGlobalCatalog 'dc.FORESTB.com' -RemoteCredential $target -TargetDe
liveryDomain FORESTB.com I have looked at the prepare move script and the linkedmailuser switch but does this apply if the account already exists in the account forest?
