I´ve setup our new Exchange 2010 Server and everything is running fine. We´ve purchased a certificate from GlobalSign which has all the necessary entries for out external access methods (OWA, ActiveSync, Outlook Anywhere). All these services are running fine without any cert errors.
But when I connect an internal Outlook client to our Exchange, I get a certificate warning. Theat´s because the Exchange shows up with its interal name and internal domain.
Do I have to extend our cert with the internal domain (which will cost another 130$) or is there any other way to get rid of this cert issue with our internal clients?
