Event Type: Error
Event Source: MSExchangeTransport
Event Category: TransportService
Event ID: 12014
Date:  08.02.2013
Time:  11:58:56
User:  N/A
Computer: EXC1
Description:
Microsoft Exchange could not find a certificate that contains the domain name EXC1 in the personal store on the local computer.
Therefore, it is unable to support the STARTTLS SMTP verb for the connector Default EXC1 with a FQDN parameter of EXC1.
 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.
