Make sure the account is enabled in Active Directory and also not hidden from Exchange Lists (for display in the GAL). I recommend making those changes on the oldest AD in the list and replicating it to the others. The "Hide from Exchange address lists" option is on the Exchange Advanced tab in the users AD entry.
Also make sure to replicate any changes you make in AD to all the Active Directory servers in the domain. You may want to wait 5-10 minutes after replicating before trying the migration again.
Then try the migration to the Exchange 2007 server again. It should work.
Let me know.

I'm having the same problem as propatho.  This is the second Exchange 2007 installation, although this one is in another site.  I was able to move one former employee's mailbox, but when I try to move any current employee I receive the same error message.

Further testing: on the 1st Exchange server I'm able to move a disabled users mailbox from Exchange 2000 server to the 1st Exchange 2007 server.  I'm reviewing permissions on both exchange servers hoping there is an rights issue.

Porourke61:

One of our issues is that we have an in house app that adds users to AD / Exchange.
Hhowever, one of the follwing actions which I performed has resolved the  problem:

Unhide from GAL.
Check that user is NOT disabled.
Check all permissions against an account that has succesfully been migrated.

Worked for me..

Good luck,
P.
