After making some certificate changes in Exchange 2016 this week, I found that the Outlook Web Access and Exchange Management websites would not work? I was presented with the normal login dialog, but after a successful authentication this happened.
This happens because the website that runs the ‘Exchange Backend’ has lost the certificate for its https binding.
Open the Internet Information Services Management snap-in > Server-name > Sites > Exchange Back End > Edit Bindings > https (444) > Edit > Select the correct certificate for Exchange.
Then run ‘iisreset’ or reboot the server.
