I am co-existing between 2010 and 2013
server 1 at Datacenter1
server 2 at Datacenter2
server 3 at Remote Site
In my existing send connector I only have server 1 and server 2 however I just sent and email from a mailbox at server 3 externally and it did not route through any of the servers in the send connector. How do I stop this ad force it to use only what's in the send connector?
