hi folks

am involved in a 300+ user migration from an old Exchange 2003 server to a separate CAS/Exchange 2008 setup (2 separate servers).

Going fine, until we hit a certain batch of mailboxes. They begin migrating, but about 1/2 through they 'fail' the move, and then are corrupted and can no longer be accessed on the old 2003 server (we havent tried too hard to recover them yet).

This happened with several mailboxes (maybe 5 out of the last 100) - but all of these boxes worked fine until we tried to migrate them. We confirmed that they were not logged in during the moves.

any ideas on why this might be happening?
