Hi all,
I am in the testing stages of a cross-forest mail migration (2008 SP2 forest with exchange 2010 SP3 to 2012R2 with 2013 Sp1)
The account is prepared with the Prepare-MoveRequest.ps1, mailbox is moved (either with new-moverequest or new-migrationbatch OR from the ECP portal) user account moves without issue, no failed items. user is prompted to restart outlook, the expectation is that when the user re-opens outlook it should be pointing to their new moved mailbox. for older mailboxes this does not work. I have to go in and manually create a new profile and search for their account.
Now the interesting part. I create a new user in the new forest, user our create user script (from the mailbox forest it finds the user, creates the local user then adds mailbox and links to the user account in the new forest) once this is done, I can wait for replication then prepare the new forest account to migration (mail enable and run Prepare-Moverquest) once I move the mailbox and reclogged in, the mailbox was pointing properly to the new exchange environment!
Any thoughts on why any older (longer then a couple days) would fail out?
any thoughts or suggestions would be appreciated!
