Recently on the process of an Exchange 2007 to Exchange 2013 migration, I happen to notice an issue with the new Exchange 2013 server. A standard SSL certificate was purchased and installed on the Exchange 2013 server recently as well. When accessing the OWA URL, all I get is a blank page as shown below :
I tried accessing the Exchange Management Shell, only to receive the error “The WinRM shell client cannot process the request“.
Upon checking the event logs, noticed the following error –
The reason for the error was later found that the new SSL certificate was not bound to the Exchange backend website. This is a new website created during the Exchange 2013 installation along with the Default website and has all the virtual directories of the Exchange services.
Steps to resolve the error :-
- Login to IIS Manager
- Select the Exchange Backend Website and click on Properties
- Select Edit Bindings
- Select https binding and click on Edit
- Bind the SSL certificate to the https binding and click OK
Confirm that you are able to login to OWA successfully and that EMS works fine.
