Fix STARTTLS SMTP error

Error:

Microsoft Exchange could not find a certificate that contains the domain name exchange.global-e.nl in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Outbound Ex 2010 with a FQDN parameter of exchange.global-e.nl. 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.

Cause:

Problem is that you have configured a wrong (not matching)  SSL certificate on your send/recieve connector.

Fix:

  • Start the Exchange Powershell
  • Get-ExchangeCertificate
  • Copy the good thumbprint
  • Enable-ExchangeCertificate -Services SMTP
  • Paste the good thumbprint
