Hello Experts -
We recently added an Exchange 2010 server to our domain to coexist temporarily with an Exchange 2003 server. I was able to successfully move all mailboxes to the 2010 server from the 2003 server and was in the process of decommissioning the 2003 server when it had a hardware failure (RAID degraded and corrupted).
I had already moved the Offline Address Book and everything seems to be working perfect but when running the Exchange Best Practices Analyzer, several errors are reported.
1. Unrecognized Exchange signature: From what I've found online, this is a bug in the ExBPA because I'm running DomainPrep version 12639 which is the correct version for Exchange 2010.
2. Routing master has been deleted
3. Cannot connect to port 25 of the routing group master
4. Cannot connect to port 691 of the routing group master
I need help with #2, #3 and #4. They are all referencing the First Routing Group on the old server. We're not planning on using Exchange 2003 again and I understand Exchange 2010 doesn't use routing groups in this way but the errors are troubling. How can I remove references to this routing group from Active Directory or point them to the new Exchange 2010 server?
Any advice is appreciated. Thanks for your help.
