Microsoft Exchange could not find a certificate that contains the domain name myserver.mydomain.local in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Exonet Payslips with a FQDN parameter of myserver.mydomain.local. 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.
