Suppose initially I set up mobility with the domain name: and my mobile devices use as the server address in its exchange connection settings.

Now if for whatever reason I need to change the external domain name to (with public IP address remaining the same).
If I use on my mobile device then I will get a certificate/server name mismatch error.

So is it possible to add as an additional domain name to the origial mobility server so that I don't have to reinstall it from scratch?
