Exchange 2007 to Exchange 2003 Send Issue
We have a co-existence of Exchange 2003 and Exchange 2007. Currently there is just a test mailbox on the Exchange 2007 Mailbox Server.
Exchange Organization:
Exchange 2003 is in a Cluster
Exchange 2007 is a CCR.
Through testing I have been able to create a user directly on the 2003 Exchange server and send and receive just fine.
I am able to move that user over to the Exchange 2007 box and it transfers fine.
After that point I am able to receive email internally and externally while the box is on the Exchange 2007 Server.
I am able to send email externally but NOT internally to the Exchange 2003 server.
Any help on this would be greatly appreciated! Thanks!

I deleted and re-created the connector but am still unable to receive mail on the Exchange 2003 system from the Exchange 2007 system. The mail just sits in the queue on the 07 system waiting to be delivered.
Run Exchange BPA and see if you get any warnings/errors on security. I have seen people in the past and change security settings and this kills the mail flow.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
New-RoutingGroupConnector -Name “Interop Exchange 2003” -SourceTransportServers “exchange2003.localdomain.
I have also seen when you run Exchange BPA there are security warnings...clear those if they exist and it should clear it up.
