We are using Microsoft Transport Services to migrate out Domino 8.5 server to Exchange 2007. I can import my users to AD no problem, but when I go to migrate the mailbox, it tells me that server x is not found. X seems to be the name of our mail server, which is "mail", but if that were the case, then why would I be able to see it in the first place. I must be missing a field somewhere. Domino is set up pretty straight forward.
