Fix Exchange Error Event ID 12014 – Manual Solutions

You get an Exchange Event ID 12014 alert because the Microsoft Exchange Server did not find a certificate and the user gets which holds the domain name mail.cnd-net.at in the storage of a local system. Therefore, it cannot support the STARTTLS SMTP verb for the connector Internet with FQDN guidelines of mail.cnd-net.at. If the connector’s FQDN is not identified, the system’s FQDN is used.

Check the connector Outline and the installed certificates to confirm that there is a certificate with a domain name for that FQDN. If an FQDN certificate exists, run Enable-Exchange Certificate -Services SMTP to identify that the Microsoft Exchange Transport service has the right to use the certificate key.

Reasons for Event ID 12014

  1. The Official Microsoft SMTP certificate is not working or may be disabled.
  2. Microsoft Exchange Server did not find a certificate, which holds the domain name mail.cnd-net.at in the storage of a local system.
  3. A user is unable to open OWA, ECP, or EMS after a self-signed certificate is removed from the Exchange Back End Website.

Errors Faced by Users

I started getting this error a couple of days ago when I had to disable the last IT guy’s account.  It seems like some permissions were attached to his name as the administrator, instead of the server’s Administrator

I keep getting these errors on my exchange 2k7 server for both our receive connector and send connector.  I followed the directions according to KB555855, and I am still getting these errors.

I am using an Extended Validation Verisign certificate if it matters.  Any thoughts on why it would still not find the certificate?
