SSL Error Exchange 2010

We recently upgraded from Exchange 2003 to Exchange 2010, My email server is called Exchange, and the external owa is mail.

I have got a certificate from Go Daddy, assigned to work with the external mail.domain.com which works fine, but internal connections to the Exchange server get a SSL error prompt. My question is this, if i were to change all references from mail to exchange, and re issue the certificate will this resolve my problems with the SSL issue, or is there another work around to this without having to change the names.

What type of certificate did you obtain? A SAN/UCC certificate (with multiple names) or a single name certificate for mail.company.com?

While the latter will work, it requires lots of configuration changes to work successfully. The Exchange community instead advises that you use a multi-name Unified Communications certificate, which contains the following names:

servername.domain.local
servername
mail.company.com
autodiscover.company.com
autodiscover.domain.local

where servername is the internal NetBIOS name of your Exchange Server, domain.local the DNS name of your internal AD domain and company.com your public domain namespace.

Once you use a certificate with those names, and providing you have not modified your virtual directory configuration away from the standard defaults, you should have no issues internally with SSL certificate prompts.
