I am receiving this error. When i look at the SMTP Send connector the FQDN name is mail.diprete-eng.com. Should I change the connector to read webmail.diprete-eng.com?
Microsoft Exchange couldn't find a certificate that contains the domain name mail.diprete-eng.com in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Send Connector with a FQDN parameter of mail.diprete-eng.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.
