I recently renewed our third party cert and found I had to remove all .local references from the certificate. Now Outlook complains about the certificate "The name on the security certificate is invalid or does not match the name of the site."
As suggested by GoDaddy I have followed this article http://support.microsoft.com/kb/940726
and pointed autodiscover and EWS to servername.domain.com which fixed a few issues but not this one.
I have also tried Installing a private CA and created a cert for servername.domain.local which did not change anything.
When I run test-outwebservices I get...
RunspaceId : 47f1ba19-2a06-48ae-a888-b2
Id : 1104
Type : Error
Message : The certificate for the URL https://internalserver.domain.local/autodiscover/autodiscover.xml
is incorrect. For SSL to work, the certificate needs to have a subject of internalserver.domain.loca
l, but the subject that was found is mail.domain.com. Consider correcting service discovery, or installing a correct SSL certificate.
I am not sure where to go from here any help would be greatly appreciated.
