I am in process of migrating Exchange 2003 from an older server to a new one. This particular question comes in regards to our Blackberry Enterprise Server. We have a few dozen people with BB's, and when I move a mailbox from the old to the new mail server, the mailbox moves no problem.
When I open up BB Manager, it sees that the mailbox has moved to a new server. However, it is not forwarding anything to the BB. I have not yet moved the BESADMIN ccount - as I assumed that was one of the last things I should do until I'm sure I have a moved mailbox working correctly.
So, to sum up - BES is not forwarding emails to a blackberry that belongs to a mailbox that has been moved to a new Exchange box in the same organization. I need suggestions.
