Details
Product: Exchange
Event ID: 10104
Source: MSExchange EdgeSync
Version: 8.0
Symbolic Name: FailedDirectTrustMatch
Message: Microsoft Exchange couldn’t match certificate when contacting %1. The connection was stopped.
   
Explanation

This Warning event indicates that the Microsoft Exchange EdgeSync service closed a synchronization session between the computer that is running the Hub Transport server role and the computer that is running the Edge Transport server role. The connection was closed because the Hub Transport server could not find a matching internal transport certificate (also referred to as a direct trust certificate) on the Edge Transport server. This event may be caused if an administrator modified the certificate on either computer.

   
User Action

To resolve this warning, do the following:

  1. Correct the problem with the internal transport certificate. For more information, see How to Troubleshoot Direct Trust Certificate Errors 1037 and 2019.

  2. Re-subscribe the Edge Transport server specified in the event description. For more information, see Subscribing the Edge Transport Server to the Exchange Organization.

If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios.
