Exchange Error 12014

Hello, I am getting this error on my 2010 Exchange server:

Application Error: 12014

Microsoft Exchange could not find a certificate that contains the domain name in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Default SERVER4 with a FQDN parameter of If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key.

This has occured since I changed the FQDN on my receive connector to match the outside DNS record.  I understand this is a certificate issue and I need a certificate that matches my new name on the send connector.  My question is can I just add another generic certificate with the new FQDN, while leaving the old cert in tact?  Is this error even that big of a deal?

All of my vendor purchased certs reside on our ISA server for Active Sync and OWA, OutlookAnywhere..... however SMTP traffic flows through a hardware firewall and not the ISA, so maybe I need another generic cert for the exchange server with a CN that matches the FQDN???

If anyone has experience in this, please let me know and Thanks!

If this error annoys you then you need to get a certificate for that, if not then you can jut ignore it, the error will be a deal when you add another hub transport server (you will need to have 2) in different sites, HUB servers will not be able to send to each other since they will need SMTP/TLS.
so in your case for a single server deployment either ignore it or get a certificate from the internal CA and assign it only to the SMTP service
