The name on the security certificate is invalid or does not match the name of the site

I recently renewed my SSL certificate for my exchange server with GoDaddy and they told me I could not include the site.domain.local SAN.
I installed the certificate and although my clients can use Outlook, they get a Security Alert with the message attached.
GoDaddy then told me I had to purchase a separate standard SSL certificate, but I don't know what to do with this certificate in Exchange - I have a self signed certificate referring to my site.domain.local which has SMTP checked (all others greyed out) but clicking renew does nothing - though it isn't due to expire for five years.
I do not understand why I am getting the attached error and what to do to resolve it.  I am also confused as to why my Outlook clients running on machines authenticated on the domain are complaining about a server within my domain...do I even need this .local certificate?
