Client has Exchange 2010 and Exchange 2003. There was a migration from 2003 to 2010. Several times a week the queue starts backing up and mail doesn't go out. I ran Mailflow tests and it shows an error communication with the bridgehead server (Exchange2003). Is there a way to get rid of this server and route all mail from the Exchange 2010?
I have found that if I restart the old server and restart all the Exchange serices on the 2010 server, mail starts flowing again.
