Hello, I had recently created a CAS array using m.domain.com as the FQDN. This FQDN was already being utilized as the client endpoint for OWA, active sync, etc..
I now get OWA errors when accessing m.domain.com/owa. It seems that when I log in I can see my main inbox, but when I try any other actions I get a pop up that states"an unexpected error has occurred and your request couldn't be handled."
I can't seem to track down the resolution to this issue.
ADDITIONAL INFORMATION:
I have installed the CAS array in preparation for DAG. We will eventually load balancing the two CAS servers with an HLB but for now I created the CAS Array so new mailbox databases would use it as the connection point for outlook. Prior to creating the CAS Array, I was already using m.domain.com as my FQDN to have client connect to it externally for OWA, Active Sync, Outlook Anywhere.
