Hi,

According to your screenshot, it seems the issue is related to Exchange, so I add the office-exchange-server-administration tag for you. If there's any concern, please feel free to let me know.

Best Regards,
Anne

Hi @VirishKundoo-7700 ,

What's the version of your Exchange?
Any changes of Exchange have you did recently? And what about OWA, is it good or has a same error?
You may got this error after installing the Security Update and it's a known issue: OWA or ECP stops working after you install a security update

Or if it's not the case, consider removing ECP virtual directory and recreating it with:

 Remove-ECPVirtualDirectory -Identity "Servername/ecp (Default Web Site)"
 New-ECPVirtualDirectory -InternalURL Https://servername.domain.com/ecp

Also check the certificate bindings both frontend and backend in IIS.

I removed the Windows-server-2012 tag cause it's irrelevant.

Regards,
Lou
