I have completed CA certificate deployment (issued from the internal AD CS) on Exchange 2013, and installed it on the Exchange server machine. I have assigned SMTP, IIS, POP and IMAP to use this on Exchange Control Panel (ECP) but when browsing to my OWA using https it returns a "Mismatched address" error. Pls help

My guess is that the address you are entering in the browser doesn't match any name in the certificate. Can you verify this please? So, that is to say, if your address is https://mail.contoso.com/owa then the name mail.contoso.com must be listed in the certificate.Jesper Bernle | Microsoft Community Contributor 2011 Awardee

Hi Prozin, Any updates? You can also run Get-ExchangeCertificate | fl and post the result here. http://technet.microsoft.com/en-us/library/bb124950(v=exchg.150).aspxFrank Wang TechNet Community Support

Hi Jesper, Thank you so much, I was not entering the FQDN on the browser, i tried with the FQDN and works like a charm

Yep, I had the exact same issue with a client ,I thought there was a cert issue however using the FWDN worked great http://www.techieshelp.com/exchange-server-2013-ssl-certificates-and-san/
