Using Exchange 2013 (e2013), SP1.
Three locations. (Let's say Location-A, -B, and C.)
Each Location is an AD site, and physically "remote" from the others.
Each location will have one e2013 server, each server running both CAS and Mailbox function.
The main location ( LOC-A) is where all external OWA and EAS will "enter" from the Internet, via a firewall.
The E2013 server there will "connect" (?) to the e2013 server for "this mailbox",...at any of the 3 locations.
What "special" configuration do we need on the 2 remote/other e2013 servers for OWA virtual directory (or similar).
It looked like it was working "out of the box".
Some users work OK, with no special changes to anything.
But some users have OWA in a "never ending wait" (browser appears to spin forever),
and that might be due to a different Language at the other locations.
I guess Exchange knows how to "internally route" the OWA traffic from the LOC-A CAS to the LOC-B CAS.
(In Exchange 2007 we called this "Exchange CAS proxy" as I recall, but not sure that term is correct in e2013.)
Thanks.
