We have two exchange 2013 servers running with a load balancer. One of my servers I can connect pop3 port 110 just fine testing with telnet but my second server will not allow the connection. I have gone over all the settings I can think of but can not find the issue. Both servers look to be configured the same. Anyone have any ideas?
I ran Test-PopConnectivity against both my servers and getting Failure about the User and the mailbox ore in different Active Directory sites. Inner Error
