I have just converted from Exchange 2003 to Exchange 2010. I installed a UCC SSL certificate from go daddy on my exchange 2010 server. The Outlook 2007 clients started getting a certificate mismatch warning because the built in certificate that the Outlook clients were pointing to was the internal name of the server (blgexchserv1.blg.local).
I did some research and came accross this post:
I attempted to change the URL of the Autodiscover services within Exchange 2010. I completed the first entry, but the outlook clients are still getting the certificate error. I did not think I needed to modify the web services url at all. I tested OWA internally and it is resolving fine. What am i doing wrong? what else do I need to do to get rid of the error.
