Hi,
We have a new deployment of Exchange 2013 CU2 V2 running on a Windows 2012 server. Everything has been running without issues and then without any real clue to why, we are now getting an issue where OWA says "Something Went Wrong" after processing your login, (it appears to process the login as if I type in incorrect details it tells me the password/username is wrong).
At the same time we have also lost the ability to run the Out Of Office in Outlook which comes back saying the server is not available and we can't seem to share calendars correctly either. (Can set Out Of Office via the Management Shell without issues).
When running a Get-Serverhealth on the OWA.Protocol it tells me the OWASelfTestMonitor is unhealthy.
I've tried re-creating the OWA, EWS Virtual Directorys and also the autodiscover but with no effect. I've also restarted the server.
Outlook 2013 and mobile phones are working fine on the server and the Exchange Admin Centre is also working without issues.
I am getting tempted to apply CU2 again to see if this sorts it but don't really like doing this on a server with 50 live users on it...
In the eventlog I can see lots of the 2 errors listed below which seems to line up. (System Log and Application Log seem to be clear of other errors or warnings.)
