Event ID: 5010

Version: 8.0
Symbolic Name: RoutingNoPfTreeRoute
Message: No route has been created for public folder hierarchy %1 in routing tables with timestamp %2. Recipients will not be routed to this public folder. Check the routing logs for further information.
   
Explanation

This Warning event indicates that the Microsoft Exchange Server 2007 transport routing engine could not calculate the route to the specified public folder hierarchy. For more information, see Managing Public Folders.

This warning may be caused by:

  • No route to the store that hosts the public folder hierarchy exists.

  • The server has not yet received configuration updates because of Active Directory replication latencies.

  • The public folder hierarchy is misconfigured.

The Folder Hierarchies container is missing under the administrative group in Exchange 2007. (The HomeMDB value is missing for public folders.)

   
User Action

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

  • Use the Get-PublicFolderDatabase cmdlet in the Exchange Management Shell to verify if one database that hosts the public folder hierarchy exists.

  • Verify the configuration of the public folder hierarchy.

  • Take no action. The messages will be routed to the Unreachable queue and delivery will be retried when routing configuration changes.

  • If you have the correct permissions, force Active Directory replication to occur immediately. An Active Directory notification causes the routing tables to be updated, and any affected messages in the Unreachable queue are resubmitted and routed to the destination server.

  • Add inheritable permissions to the appropriate mailbox store object, and make sure that the Exchange Servers group has the correct permissions. For more information, see Troubleshooting Mail Flow from Exchange 2007 to Exchange 2003 When E-Mail Messages are Stuck in the Queue.

  • Use ADSI Edit to create the Folder hierarchies container under the administative group in Exchange Server 2007. For more information, see Troubleshooting Mail Flow from Exchange 2007 to Exchange 2003 When E-Mail Messages are Stuck in the Queue.

  • Make sure that the msExchOwningPFTree attribute is associated with a public folder tree and that the location of the CN=Public folders container is under the Folder hierarchies container.
