Exchange 2010 Edge Server Mail relay from Site A to Site B
Posted on 2013-11-22
In our exchange 2010 setup we have 2 sites and an edge server at each site with separate internet connections.
What is the best method to get Site A to send mail through Site B edge server if Site A edge server goes down and vice versa please?
We have HUB/CAS at both sites and MAIL Servers.
I am able to see the edge servers from both sets of HUB/CAS servers, I have also done an edge subscription to both edge servers site related and cross site fine with the correct ports open etc.
But when I switch off the Edge server at Site A it cannot send main to Site B edge.
edge servers have the default smtp receive and send connectors only.
Do I need to set others up to achieve this?
Just trying to find out where I am going wrong.
