Neither of those is the correct way to establish internal mail flow, and in fact you’re more likely to break internal mail flow if you try either of those things.
The Exchange 2003 servers within a routing group could talk to each other just fine, but you needed to create routing group connectors to get the servers in two different routing groups to talk to each other. This issue comes up fairly regularly, so I figured it’s time to write a post about it, as well as some of the other common issues I see in the field.įor the connector issues, I suspect part of the misunderstanding in this area is that back in the Exchange 2003 era there was the concept of routing groups and routing group connectors.
I hear from quite a lot of people that break their internal Exchange mail flow by configuring receive connectors and send connectors.
