My battle with Exchange continues…
After a day of messing around with the configuration (details to come soon). I restarted my Exchange 2010 Server. All was working as expected, so thumbs up and smiles all around. And then… it happened! I attempted to access web-mail (OWA).
The main Outlook Web Access page loaded without any issues. So I logged in and after clicking Sign in I was presented with a blank page pointing to auth.owa. What broke? I didn’t do any updates. Attempting to test using Test-OWAConnectivity in the EMC didn’t give me much info to go on.
I later looked into the services and “wow, Microsoft, for-real guys” … Forms Based Authentication to a seperate Service called Microsoft Exchange Forms-Based Authentication Service.
Starting this fixed my issue. I am puzzled why this didn’t start with the server, because its set to automatic. I will do a little more digging and if I find something I’ll report back.
