"The name on the security certificate is invalid or does not match the name of the site" error in Outlook
Posted on 2014-10-20
For our email we use Exchange 2010 and a separate windows server that services OWA requests. The SSL cert for OWA recently expired (after 5 years, so this is something that we don't do often) and instead of installing it directly on the OWA server (IIS), by mistake, we installed it on the Exchange server through the EMC. After realizing what I did wrong, I revoked the cert, issued a new one and installed it the right way.
When accessing the webmail, all works well and it shows the right cert. But now all Outlook clients get 2 popup messages with the error "The name on the security certificate is invalid or does not match the name of the site" and when I click to view the cert, it shows the one I revoked and manually removed from EMC and Certificates MMC snap-in (Personal and Trusted Root).
My question now is if I missed a spot where this revoked certificate could still be residing? And how to suppress these errors?
