We just renewed our exchange 2010 ssl and since you can't use internal address on the SSL we are getting an error when outlook is connecting to exchange. I've changed all internal URL to use our webmail FQDN which is on the SSL cert. We are still getting the following error (see snap shots below) that references the original internal netbios name (server.domain.loc)
One thing i noticed when testing the new internal URLS is it asks for a username/password when going to it with a browser. when i use the internal netbios name it loads right up....
