Sorry for this noob question...
I have domain *.contoso.com shared between serverA.domain.local and serverB.newdomain.local on 2 Exchange 2010 servers.
On serverA.domain.local I set up an internal send connector for *.contoso.com to smarthost serverB.newdomain.local however for a mailbox that was moved earlier I get a failed routing error in the logs.
How do I resolve this please?
