Exchange 2010 SSL Certificate Renewal, no Subject Access Names allowed for internal domain names.

Hi,

Up until recently GoDaddy have allowed local names in their SAN for SSL certificates. This meant we could have

external-ex01.ourcompany.com/owa

and

internal-ex01.ourcompany.local/owa

on the same certificate. Unfortuantely CA's have now preventing the renewal on SANs that are not FQDN. We have created Self-Signed Exchange 2010 certificates with the local names and rolled them out to our users via GPO. However Outlook 2010 is still looking at the SSL certificate for the external names.

How do we resolve this?

This is a very common problem and easily resolved.
You just need to use the external host name internally via a split DNS system.

Forget about using self signed certificates, waste of time.
