Did you try the other protocols ?
Do you mean the other protocol like DAV instead of EWS or like CalDAV instead of SMTP? My Exchange server only supports EWS so I'm stuck with that. CalDAV seems to work just fine though and I can manually access my /ews/exchange.asmx endpoint. I have not tried LDAP or IMAP recently, I will give them a shot and report back.
Got me on the right track. In the end it was an authentication problem. For several years I had been authenticating with the username: user@fqdn.edu which was working fine. Apparently someone flipped a switch somewhere which not requires that I authenticate as domain\username so I had to update my username in my client configuration which cleared up the problem. Thanks!
