I have a server that was migrated from SBS 2003 to SBS 2008. The old server was demoted and the migration completed except for uninstalling Exchange. It has not been turned on for about 6 months.
When I run the Exchange BPA, I see:
Exchange Administrative Group with the new server name
First Administrative Group with the old server name
If I run the Routing log viewer, I see:
First Routing Group is NEWSERVER-OLDSERVER and the old server is still listed under 'Servers' along with the new server.
Under Routing Group Connectors, I see:
Mail has seemed to be flowing fine until recently a couple employees have stated that some of their emails they send are not getting to the recipient and I'm thinking it could be these routing connectors and references to the old server. Another employee can send to the same recipient and it goes through.
How do I get this cleaned up so the old server references are gone from Exchange on the new server?
