I have an issue with getting 12014 errors. I get them about every 15-20 minutes or so. This has been happening ever since the server is setup. Everything is working fine so it seems cosmetic, but I would like to resolve the error so it doesn't fill up my event log. Error: Microsoft Exchange could not find a certificate that contains the domain name exchange.butlermachinery.com in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector * with a FQDN parameter of exchange.butlermachinery.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. Single server, running 2007 Exchange SP2 RU5 EE , Windows 2008 SP2 EE Thanks!

The error means what it says. The server cannot find a certificate with the FQDN value specified in the certificate store. That usually means the SSL certificate isn't a UC type with the additional names, or it is, but none of those names are the FQDN on the connector specified. To fix - get a certificate with the name included, or change the FQDN on the Connector. If you haven't deployed a commercial SSL certificate then I have instructions on my blog here: http://blog.sembee.co.uk/post/Exchange-2007-and-SSL-Certificates-Take-2.aspx Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK?
