I have my Exchange server behind an IIS Server which resides in the DMZ. I would like to either 1) install some Exchange role (I'm VERY new to Exchange) on the IIS server in the DMZ or create a proper reverse proxy rule to the internal Exchange server.
I've found a few guides but they have not been terribly consistent or newbie friendly. If anyone could give some recommendations of articles/kbs which will explain which option to use or have a detailed walkthrough I would be extremely grateful!
