Exchange 2007 Connector Certificate Error

Posted on 2007-10-08

Hello Experts,

I receive this error on event viewer:
Source: MSExchangeTransport
Microsoft Exchange couldn't find a certificate that contains the domain name in the personal store on the local computer. Therefore, it is unable to offer the STARTTLS SMTP verb for any connector with a FQDN parameter of Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for every connector FQDN.

I think the only certificate i have was created with the installation of exchange 2007 for srvmail.mydomain.local. Can anyone explain how resolve this error? I supouse that i have to install a local CA and then create a new certificate, but how i install this on exchange 2007 connector?

    That is a common error. You can ignore it - I do at the moment.
    Basically Exchange is looking for an SSL certificate on the server that matches the FQDN you have put on to either the Send or Receive Connector. You can either go and purchase an SSL certificate that has that name on it or simply ignore the message. A self generated certificate is not enough because no one will trust it.

    I wouldn't suggest using the certificates as those do not have a very high trust level. You would need to get one that is widely trusted. RapidSSL or GoDaddy's certificates are widely trusted.
