Microsoft Exchange could not load the STARTTLS certificate from the local store because it did not match the FQDN from the connector configuration.

Explanation

This Warning event indicates that there is a problem loading a certificate to be used for STARTTLS purposes. Generally, this problem occurs if one or both of the following conditions is true:

  1. The fully qualified domain name (FQDN) that is specified in the Warning event has been defined on a Receive connector or Send connector on a Microsoft Exchange Server 2007 transport server, and no certificate is installed on the same computer that contains the FQDN in the Subject or Subject Alternative Name fields.

  2. A third-party or custom certificate has been installed on the server and it contains a matching FQDN. However, the certificate is not enabled for the SMTP service.

Transport Layer Security (TLS) functionality requires that a valid certificate is installed in the computer's personal certificate store.

User Action

To resolve this warning, you must first determine the cause of the Warning event. The following possible causes exist:

  • A certificate does not contain the FQDN of a connector on the computer

  • The certificate is not enabled for the SMTP service.

  • Both these conditions are true.

Troubleshooting

To troubleshoot this issue, you must first examine the configuration of the certificates installed on the Exchange server and the configuration of all Receive connectors and Send connectors installed on the server. The following commands are used to view the configuration:

Get-ExchangeCertificate | FL *

Get-ReceiveConnector | FL name, fqdn, objectClass

Get-SendConnector | FL name, fqdn, objectClass

Note   To display the services that are enabled for the installed certificate, you must use the asterisk (*) when you run the FL argument on the Get-ExchangeCertificate cmdlet. The Services values will not display if the * is not specified in the task parameters.

Run the commands and compare the FQDN that is returned with the Warning event with the FQDN that is defined on each of the connectors and with the CertificateDomains values that are defined on each of the certificates. The CertificateDomains value is a concatenation of the Subject and Subject Alternative Name fields on the certificate.

The goal is to verify that each connector that is using TLS has a corresponding certificate that includes the connector's FQDN in the CertificateDomains values of the certificate. Note any connectors that are enabled for TLS but do not have a corresponding certificate where the connector FQDN is in the CertificateDomains values of the certificate.

Inspect the Services value on each certificate. If you are using a certificate for TLS, it must be enabled for the SMTP service with a Services value of SMTP.
