Rule Path

Microsoft Exchange Server/Exchange 2010/Common Components/Hub Transport and Edge Transport/Transport

Rule Name

Inbound direct trust authentication failed for a certificate. Make sure the EdgeSync service (MSExchangeEdgeSync) is running.


This Error event indicates that Domain Security, which uses mutual Transport Layer Security (TLS) authentication, failed for the connection attempt by the indicated source IP address. Domain Security requires that an Edge Subscription is configured for the receiving Edge Transport server.

For more information about Domain Security, see Understanding Domain Security.

User Action

To resolve this problem, do one or more of the following:

Verify that the Edge Transport server is subscribed to the Microsoft Exchange organization. For more information, see Managing Edge Subscriptions.

  • Verify that the Edge Transport server is receiving synchronization updates through the EdgeSync process. You can check whether the Microsoft Exchange EdgeSync service is running on all Hub Transport servers in the subscribed site. You can use the Test-EdgeSynchronization cmdlet in the Exchange Management Shell to verify EdgeSync results.

  • Verify that the domain is included in the list of remote domains that is specified in the TLSReceiveDomainSecureList parameter and in the TLSSendDomainSecureList parameter. These parameters are configured on the TransportConfig object for the Exchange organization. You can use the Get-TransportConfig cmdlet in the Exchange Management Shell to view these parameters. If the domain is not included in the list, you can use the Set-TransportConfig cmdlet to add the domain to the list. These parameters are synchronized to the Edge Transport server during the EdgeSync process.

  • Review other related Error events and Warning events in the Application log. These related events may help you find the cause of this problem.

  • If the recommended steps do not resolve this problem, contact Microsoft Customer Support Services. For more information about how to contact support, visit the Microsoft Help and Support Web site.
