The Microsoft Exchange Server 2010 Management Pack for System Center Operations Manager monitors the Windows Application log on computers running Exchange 2010 and generates this alert when the events specified in the following Details table are logged.

To learn more about this alert, in Operations Manager, do one or more of the following:


Product Name


Product Version

14.0 (Exchange 2010)

Event ID


Event Source

MSExchange EdgeSync

Alert Type


Rule Path

Microsoft Exchange Server/Exchange 2010/Hub Transport/EdgeSync

Rule Name

EdgeSync failed to confirm the credentials for a replication account on a subscription server.


This Error event indicates that the Microsoft Exchange EdgeSync service could not validate the future replication account credentials that are required to replicate Active Directory data to the Edge Transport server. The replication account and the target Edge Transport server are specified in the event description.

This Error event does not indicate that the replication account credentials that are currently being used are invalid. Instead, it indicates that the set of replication credentials that must be used next is not valid. EdgeSync performs this proactive check to verify that it can log on with the new credentials 15 days before the Edge Transport server will switch to the new credentials.

This Error event may be caused if the future Edge Transport credentials have not been correctly propagated to the Active Directory Lightweight Directory Services (AD LDS) instance on an Edge Transport server.

For more information about EdgeSync, see Understanding Edge Subscriptions.

User Action

No immediate user action is required. However, you must resolve this error before it becomes a problem. To resolve this error, do one or more of the following:

  1. Make sure that the Microsoft Exchange Credential Service (EdgeCredentialSvc) is running on the target Edge Transport server.

  2. Make sure that the replication account credentials are correctly propagated to the AD LDS instance on an Edge Transport server. To do this, run the Exchange Management Shell cmdlet Start-EdgeSynchronization. This cmdlet forces EdgeSync to replicate the replication account data to the target Edge Transport servers.

If this event is still logged after you perform these steps, review the Application log for related events. For example, events that occur immediately before and after this event may provide more information about the root cause of this error.

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.
