Exchange hub transport “Mail.que” file large in size

  1. Open exchange management shell and run “Get-TransportServer ” HUB01″ |fl
  2. Here, look for PipelineTracingEnabled. This should be set to False. If not, run
    Set-TransportServer HUB01 -PipelineTracingEnabled $False
  3. Now run “Get-TransportConfig” and ensure that
    MaxDumpsterSizePerStorageGroup is in MB’s and not GB’s

    MaxDumpsterTime : 7.00:00:00

    If not, run

    Set-TransportConfig -MaxDumpsterSizePerStorageGroup -MaxDumpsterTime
  4. Now run “Get-Queue” and take a look at the count of messages in HUB01
  5. Goto services.msc and Pause the Microsoft Exchange Transport service
  6. Again, run “Get-Queue” and ensure all pending messages are “zeroed” out
  7. Once messages pending becomes zero, stop the Transport service
  8. Move the mail.que file and all others to a new folder in the same location
  9. Start the Transport service
  10. Take a look at the queue again
  11. You should see that messages would have started getting delivered
  12. Now you can backup or safely delete the old mail.que file
