Yesterday I noticed an expired certificate in and had event logs complaiining about it. After I replaced the expired cert with a new cert I began to receive a new Event ID: 12014. Which contains:
Microsoft Exchange could not find a certificate that contains the domain name data1.xxx.com in the personal store on the local computer. Therefore it is unable to support the STARTTLS SMTP verb for connector DefaultInternet w/ FQDN parameter of data1.xxx.com. Verify the connectors configuration and the installed certificate to make sure there is a certificate w/ a domain name for the FQDN.
My questions are:
1. How do I go back and look at the cert that had expired to see how it was configured? I am thinking that my new cert did not have the correct parameters for data1.xxx.com
2. The data1.xxx.com is our external DNS pointer for our MX records for xxx.com. So by the Event errors I am guessing that I need to take care of this error asap.
3. If i install/redo the cert; it is necessary to verify connectors and such. This Exchange has been in place for several years so I now it is set up and configured correctly.
