I have an Exchange 2013 server and I install a certificate from godady.com so it resolved to mail.mydomain.com
Internally or externally if I go to https://mail.mydomain.com/ecp it work perfect and I do not get prompted to accept the certificate but internally if anyone start Outlook they get 2 certificate error. Both say that the name does not match the one on the certificate.
If I click view certificate it show the proper one from godady.com but the name outlook try to resolve is first one exchangename alone then exchangesrvname.internaldomain.local.
I did change the internal URL on the virtual directory for ECP, OWA and EWS to match the mail.mydomain.com that is on the certificate and also made the changes on external ling for outlook anywhere but I still get those 2 certificate errors. Any idea were else I should look for?
