I have a domain with two exchange servers. One on 2000 and one on 2003. I an wanting to move all the mailboxes from the 2000 to 2003 Exchange. I have moved one mailbox to the 2003 exchange server. When opening the outlook client for the first time it said it needed restarting as the mailbox had moved, fine, but now that account will only send externally.
Mail sent to any mailbox on the 2000 Exchange server appear to just get lost. It appears in the queue and then looks to get sent to the 2000 exchange server but then is not received by the recipient if it is any of the 2000 mailboxes.
