We are at the point that we can move all SMTP over to Exchange 2010. We can send email to external domains, but can not receive.
The firewall rules have been modified, Email filter DMZ Smtp smart connector has has been changed to new Exchange server, and Receive and Send connectors created on Exchange 2010, what else could we be missing. The SMTP traffic is still going through our Exchange 2003 server.
Do we have to use the Remove-RoutingGroup Connector to remove the connection?
Can we did the same in the GUI?
