We installed one Exchange 2013 server named EXCH1 with both CAS and Mailbox on it. Everything was working correctly.
So I installed a second CAS/Mailbox server named EXCH2.
After that, one user started reporting this error. {Outlook is unable to connect to proxy server exch2.domain.com. (Error Code 8).
(Question 1) Does Exchange 2013 CAS load balance automatically? Because all of the DNS and external URLs point to EXCH1 (going through a firewall and such of course)
So why is a user being pointed to EXCH2?
So I made sure all the VirtualDirectories in EXCH2 matched those from EXCH1. Also imported our wildcard cert.
(Question 2) Should that make the error go away or are there other things I need to do? It's hard to tell if the error is widespread because only 4 users are on the new Exchange environment right now.
