Explanation

This Error event indicates that the Microsoft Exchange Server 2007 transport routing engine can’t calculate a route to the target Active Directory directory service site. Because no route is available, the messages will be delivered to the Unreachable queue. This event may occur when one of the following conditions is true:

  • The specified Active Directory site is not included in any IP site links.

  • The IP site link for this Active Directory site is not configured correctly.

  • The Active Directory site is not configured correctly.

  • There are no Hub Transport servers located in the Active Directory site.

User Action

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

  • Verify that the specified Active Directory site is included in an IP site link.

  • If the specified Active Directory site was created recently, this error can be caused by replication latency. The affected messages will be resubmitted to the categorizer and rerouted when the routing tables are updated.

  • Verify that the Active Directory site that is specified in the error message text contains at least one Hub Transport server. If the Active Directory site already contains a Hub Transport server, make sure that it is reachable on the network.

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

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