Exchange 2010 to Exchange 2007 mail routing
Posted on 2012-09-20
I am currently in the process of testing my Exchange 2010 Server in preparation for a migration.
I issue I have is that I can send mails to users who are on the Exchange 2010 server to each other, but if I try to send mails to users on the legacy Exchange 2007 server, the messages are just stuck in a queue.
I have configured both HUB Transport server receive connectors to accept mail from each other, but still no joy.
I have tried telnet to each server and that works fine.
Can anyone shed any light on something I haven't done?
Help really appreciated.
