Mail not flowing from 2010 to 2003
Hi all I am practicing doing a transition from exchange 2003 to exchange 2010. I am at the point where I am in coexistence, but mail is not flowing from users on 2010 to users on 2003. I have created a Routing Group Connector by running the New-RoutingGroupConnector command, but still no luck. I know when the first hub is introduced to the domain, a RGC is created automatically. I deleted that one as mail was not flowing with it in place either, so I removed it and created the new one. I looked in the Queue Viewer and there is nothing there. Emails leave outlook and return no detailed except after a day or so I get a delayed delivery message.
Delivery is delayed to these recipients or groups:
03 rambo (email@example.com)
Subject: test from 10 to 03
This message hasn't been delivered yet. Delivery will continue to be attempted.
The server will keep trying to deliver this message for the next 1 days, 2 hours and 17 minutes. You'll be notified if the message can't be delivered by that time.
