Getting HTTP error 500 after a successful login to Exchange Administrative Center, I'm cluess where OWA writes HTTP 500 errors to.
I can neither see any relevant entries in the Windows Event Log, nor find any log files beside the standard IIS logs that contain no further details.
Being an ASP.NET application, I would have expected to see some log files with detailed stack trace and exception/error messages for the HTTP error 500.
My question:
Are there any log files that contain details about an HTTP error 500 in OWA/Exchange Administrative Center?
According to your description, you could refer to the following KB( which also applies in Exchange 2016). Follow the steps in the article. Exchange 2013 Unable to access ECP Encounter “500 Unexpected Error”
Also, what about checking the IIS log in C:\inetpub\logs\LogFiles\W3SVC1
