Microsoft Exchange could not find a certificate that contains the domain exchange2010.mydomain.loca
l in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Default EXCHANGE2010 with a FQDN parameter of exchange2010.mydomain.loca l. If the connector's FQDN is not specified, the computers 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.
