I recently renewed our SSL cert for our Exchange Server 2010 and everything is working fine. However I have been receiving Error 21014 in the Event Viewer Application Log consistently. When I look up the error on Microsoft's website it shows how to fix this. See Microsofts Event Viewer Details below

Microsoft Exchange could not find a certificate that contains the domain name orsc-email2.orsurety.com in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Outbound MXLOGIC Mail with a FQDN parameter of orsc-email2.orsurety.com. 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.

I verified that the services configured are assigned properly.

I'm not sure if I should run the "Enable-ExchangeCertificate - Services  b/c they are already added. Any help would be appreciated

Does the host name listed appear in your SSL certificate?
If not, have you changed your SEND Connector to match the name that does appear on the SSL certificate?

I see this all the time and the easiest fix is to run

new-exchangecertificate

(no switches or other options).
That will generate a new internal SSL certificate for just TLS/SMTP traffic. When you run that command you will get a prompt about replacing the default SMTP certificate. Accept that and then restart transport.

Do you have self signed certificate?
If that is creating this error you can ignore easily

MAS - I do have a self signed ssl cert thru godaddy.

Simon - When you say host name your talking about the Exchange server name correct? Because on the cert shows 1 of our External DNS A records.

When I goto the Personal Certificates It shows the godaddy as well as 2 others. The 2 others being the hostname of the server. When I view those certs it says This CA Root certificate is not trusted. install cert in truested root certification authorities store. Not sure if those need to be there

Host name being what you have on the certificate. It may or may not be the same name as your Exchange server - in most cases it is not.
If that is the case, then generate a new internal Exchange certificate, as per my response above - so you have two certificates being used.
