Hello, I'm interested in configuration the connector between exchange 2003 server and exchange 2013. Both servers are in the same network of the corporation and in different forests. I configured Trusts and DNS between domains and configured the connectors between the servers in accordance with the documentation to help on technet.
As a result, I can send mail from the server 2003 to 2013, but can not receive mail from 2013 exchange server on exchange 2003. Could this be the reason that 2003 exchange not support email sent from 2013 exchange or cause configuration connectors?
In Message Queue Server 2013 an error 451 4.4.0 Error Encountered while communicating with primary target IP adress: "421 4.4.2 Connection dropped due socketerror.
I was looking for information about this error, but on the domain and exchange server all settings are OK.
Thanks in advance for your reply!
