There shouldn't be a RGC created on the Exchange 2003 server. There should be a single Interop RGC, bidirectional, that is used by both 2003 and 2007, created on the 2007 server. In fact, the "grayed out" probably means just that - that the RGC was created on the 2007 server. The set-routinggroupconnector cmdlet is probably what you need. Get-routinggroupconnector will show you the current settings. Regards, Michael B.

I moved one mailbox and tested mailflow from Exchange 2003 to 2007 but got a System Undeliverable message 5.3.5. From what I can tell it is because the routing connector that was created on the Exchange 2003 server is pointing to the default SMTP Virtual Server which is disabled because the person who originally set up the server was unable to get the default one to start without failing so a new one was created. I was going change the routing connector to point to working SMTP Virtual server but all routing connector options are greyed out. Any suggestions on how to correct this to get mailflow working? Thanks in advance.
