I am running Exchange 2010 on an IIS 6 server. My certificate is expiring, so I went and got a new UCC certificate. The valid domains were:
When I renewed the certificate I was not allowed to renew the "email-01" and "email-01.domain.local" because they can't be verified. I didn't think anything of it at the time.
However this morning I installed the new certificate and now my users are getting a warning when opening outlook that the name on the certificate doesn't match. They are connecting to email-01.domain.local.
I understand what is happening, but not sure of the best resolution.
