I installed two new Exchange 2010 servers in a domain that already had an one Exchange 2003 server in it. Both 2010 servers are configured with identical roles but the DB is only one one.
As a test, I moved one user over from 2003 to 2010 and the move went fine. My only problem is that, although he can send mail out to the internet, he is not able to receive any mail at all.
The installation seems to pulled all appropriate connector settings so I'm a bit miffed why it isn't working. I do know, however, that the SMTP connector on the 2003 server seems to be essential to getting any mail in or out of the network. If it's turned off, no mail flow at all. Shouldn't this be running on 2010?
