Exchange 2010 SP2 SMTP routing out both CAS servers
Posted on 2014-12-15
We have an Exchange 2010 SP2 environment with 2 Exchange servers running Hub Transport, Client Access roles; 2 Exchange servers running Mailbox Role. We recently moved all the servers into one site for audit/security purposes. My question is: when moving these offsite, I noticed that email flows outbound through either CAS server. Is this by design automatically to load balance the traffic between the CAS servers when the servers are at one site?
