Rule Name

A secure connection to a domain-secured domain couldn't be established because validation of the TLS certificate failed.


This Error event indicates that a certificate validation error has occurred with a domain that is configured for Domain Secure e-mail.

User Action

To resolve this error, you must perform one of the following tasks:

  • Disable Domain Security for the domain.

  • Fix the certificate validation error. For more information, see Troubleshooting Certificate Validation Errors

Disabling Domain Security

To disable Domain Security for the remote domain, you must remove the domain name from the TLSReceiveDomainSecureList parameter in the Set-TransportConfig cmdlet. If you have not configured dedicated Receive connectors for the domain, you can disable Domain Security for that domain by removing the domain name from the TransportConfig object.

If you are using dedicated Send connectors and Receive connectors for the domain-secured mail flow path, disable the connectors by setting the Enable parameter to $False using both the Set-ReceiveConnector cmdlet and the Set-SendConnector cmdlet. Mail flow from this particular domain will then flow through your default Send connectors and Receive connectors.

For more information, see the following topics:

  • Set-TransportConfig

  • Set-ReceiveConnector

  • Set-SendConnector

  • Understanding Domain Security

For More Information

If you are not already doing so, consider running the Exchange tools created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. To run these tools, go to the Toolbox node of the Exchange Management Console. To learn more about these tools, see Managing Tools in the Toolbox.
