Was this a greenfields installation of Exchange 2007?
If so, it isn't supported to make that move. For lots of reasons. If they had Exchange 2000/2003 before, and upgraded, and just removed the Exchange 2003 server, off the top of my head, I think that should work. Regards, Michael B.

Could this be as simple as installing E2k3 in the same site as the E2k7 server and moving the mailboxes? Make my day please.
