Hi I'm facing this problem since days now and I've spent a lot of time searching and troubleshooting with no luck.
- DC: Windows Server 2012
- Exchange: Exchange Server 2013 CU2 V2 (with its security updates), installed on Windows Server 2012.
Exchange Server / OWA was working fine after the installation and configuration for about two months and then this error occurred. Whenever going to https://ExchangeServer/owa it prompts you for the credentials and when logging in you'll get the error page":-( Something went wrong" error code 500. ECP is working fine, the problem is only with OWA.
Troubleshooting (with no luck),
- Recreated ECP, OWA, EWS Virtual Directories, and resetted the Autodiscover virtual directory.
- Created a new self signed certificate and use it with the exchange services.
When using "Test-WebServicesConnectivity" I'm getting Scenario EWS: GetFolder Failure. And in the Get-HealthReport OWA.Protocol alertValue showing "Degraded" and OWA alertValue "Uknown", EWS.Proxy and EWS alertValue "Degraded".
Please advice and thank you in advance.
