I am in the process of testing a migration from Exchange 2007 to Exchange 2013. There is a single multi-role 2007 server (running on a W2008 DC) to migrate to a single 2013 server running on a W2012 domain member.
2007 is at SP3 rollup 10
2013 was installed at CU2
The problem is that mail fails to be routed from 2007-2013, and builds up in a queue with the 5.7.3 error.
Routing from 2013-2007 works fine, as does outbound from either.
Having read other reports of this symptom and resolutions, I created a dedicated hub transport role receive connector on 2013, scoped to the IP of the 2007 server, configured for TLS and Exchange Server Authentication, with Exchange Server permission groups, and enabled verbose logging on it and the intra-organisation send connector on the 2007 system.
I include the log for a session from both the send/receive below.
My observation, comparing with a (working) log in the opposite direction, is that Exchange 2013 is only advertising X-EXPS GSSAPI NTLM - whereas 2007 adds X-EXPS ExchangeAuth.
I also note that the send connector only logs the inside of the STARTTLS.
The receive connector logs the following:
