I have a migration in progress, just about ready to wrap it up but I am having a problem with email flow. The new server has all of the users email boxes, the old server has the two default email boxes left. SMTP traffic is ported to the new server, the send and receive connectors are working fine. So the old server is just about ready to uninstall. However, when I delete the Interop RGC, the old servers queue is still picking up a few emails, which of course stay in the queue until I add another Interop RGC. I have deleted the MX record that points to the old server. Is this common behavior?
Thanks - Wayne
