Recently added a branch office to connect to the main office with a hardware VPN. Joined the local server to the domain and all networking works fine.
The Exchange 2010 server is located in the main office. Outlook clients locally connect fine. Outlook clients externally can connect from the outside using the certificate.
Outlook clients across the VPN get "The name on the security certificate is invalid or does not match the name of the site". Press OK and all works ok. At the top of the Secirity Alert it does show the correct Exchange server, but when you view the GoDaddy certificate it lists the external.domain.com address.
I know it has something to do with the branch office being on a different network across the VPN. Suggestions?
