Event ID


Event Source


Alert Type


Rule Path

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

Rule Name

No source routing group was found in the routing tables for the specified connector. Therefore, the connector has been skipped.


This Error event indicates that the specified routing group connector is configured to use the specified routing group as the source routing group. However, that routing group does not exist in the referenced routing table. Microsoft Exchange will not include this connector in server route information. This error may be caused by Active Directory  replication latency. For more information, see Understanding Message Routing.

User Action

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

  • Verify the routing group connector configuration, and make sure that the source and target servers configured for the routing group connector are valid.

  • Take no action. When the Active Directory notification is received, the routing tables will be updated to include this routing group connector.

  • If you have been granted the correct permissions, you can force Active Directory replication to occur immediately.

  • 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 others. 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 Technical Support, be sure to review your organization's guidelines first.
