Hi Guys
I have a single server Exchange 2013 SP1 (CAS + MBX). I have an Exchange 2007 SP3 Edge on my DMZ. Mail flow works just fine right now. However, I implemented a Exchange 2013 SP1 Edge with the aim to decommission the Exchange 2007 Edge. However, when I turn off the Exchange 2007 Edge and redirect my firewall traffic to the new Edge, I can only get outgoing mail to work. The incoming mail is not working.
I have seen articles where I need to change the port on the Inbound Send Connector to 2525. I am not sure if this is necessary, because it works with the 2007 Exchange Edge with the default port 25.
Any advice is appreciated.
