  • Verify that the Edge Transport server is receiving synchronization updates from the Microsoft Exchange EdgeSync service. You can use the Test-EdgeSynchronization cmdlet in the Exchange Management Shell on a Hub Transport server to verify EdgeSync results. For more information, see Test-EdgeSynchronization

  • Review the Application log and System log on your Exchange 2010 servers 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.

  • Resolve your issue by using self-support options, assisted support options, and other resources. You can access these resources from the Exchange Server Solutions Center. From this page, click Self-Support Options in the navigation pane to use self-help options. Self-help options include searching the Microsoft Knowledge Base, posting a question at the Exchange Server forums, and other methods. Alternatively, in the navigation pane, you can click Assisted Support Options to contact a Microsoft support professional. Because your organization may have a specific procedure for directly contacting Microsoft Product Support Services, be sure to review your organization's guidelines first.
