I have a Exchange 2010 system that was setup on a dot local domain. With the change of how certificates can be create I was unable to recreate the cert with the dot local domain name in it. This is causing a certificate error for my end user when working inside the domain. How can I configure outlook to work with the external cert without having to reconfigure the domain or completely reconfigure exchange. I understand I will have to make changes inside exchange but I have 50 users that I will have to walk to each machine and change if it is to large of a change. What can I do to fix this.
