I setup Exchange 2007 on my server. The domain is usmsol.local. I created a certificate through CA Cert (thanks Geffy) in the name mail.usmsol.net since that is how I will be accessing OWA. However, when I open Outlook 2007 I get a certificate error since the name of the server (usm-fusion.usmsol.local) doesn't match the name on the certificate (mail.usmsol.net). How do I resolve this or prevent Outlook from displaying this message? I've already installed both the root certificate and the server certificate. Furthermore, you cannot add .LOCAL domains to the certiificates on CA Cert. If I go through VeriSign will I be able to add both usm-fusion.usmsol.local and mail.usmsol.net? Any help/input is appreciated. Thank you.
