Exchange 2010 Edge Server Mail relay from Site A to Site B
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.
Thanks!

Have you added both edge servers to the cas's send connector?

Is that route mail through smart connector?
Yes that would be the setting with an edge transport server

Going on what you have mentioned there, can I keep the Sync at the sites with edge then add a 2nd send connector to the edges aswell?
OR can i sync the 2 edge servers at both sites to Site A, then in a DR scenario manually change over to site B if required?

I don't think there is a way to do a fail over situation (don't quote me on that im not 100% sure) but i think the only way is to either have them balance by using a single send connector with both edge servers in there. i think it uses the first available for its load balancing so i would think most of your traffic will still go to the local server anyways.
Both are possible. Syncing with both the Edge Servers with one AD site is definitely possible. Creating send connectors manually is also possible.
But yeah, in case of a failure of a smarthost on the connector (provided there are no multiple smarthosts), it always will be manual actions to make the mails flow again.
