As the title suggests, I'm having issues getting my SSL security certificates in Exchange 2013 validating Outlook from both internal and external connections. I can't seem to make the certificate accepted for internal (servername.domainname.local) and external (mail.domainname.com) outlook connections. On one certificate with servername.domainname.local as the primary address the internal Outlook clients connect just fine but external clients refuse to connect via Outlook Anywhere, then when I change the certificate to have mail.domainname.com as the primary, Outlook anywhere connects fine but internal clients complain that the certificate name is invalid but still allow the connection. The certificate is a single domain certificate issued via GoDaddy.
Help me Experts-Exchange, you're my only hope.
