Rule Name

A message from a domain-secured domain could not be authenticated because the server did not use Transport Layer Security (TLS).

Explanation

This Error event indicates that a message received from a remote domain configured locally as a domain secured domain in your Microsoft Exchange organization was received without using TLS. For Domain Secure messaging to function, your domain must also be configured as a domain secured domain in the sending Exchange organization.

User Action

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

  • Disable Domain Security for the domain.

  • Contact the administrator of the domain and request that your domain be configured correctly for Domain Secure messaging.

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 on both the Set-ReceiveConnector cmdlet and the Set-SendConnector cmdlet. Mail flow from this specific domain will then flow through your default Send connectors and Receive connectors.
