Hello, EE. I'm curious: What is the proper way to publish OWA (Exchange 2010) services to the outside world? I don't want to open ports to a server on the inside network, and I've read that the OWA server needs unrestricted access to Active Directory, potentially complicating firewall rules if I put the OWA server in the DMZ.
So, what's the solution? Reverse proxy? I'm looking for real world "I've done it this way, and its awesome" solutions.
