The steps to follow are:

  • Open the Exchange Management Console (EMC), click on the Toolbox Container and select the Queue Viewer option

Queue Viewer

  • Check the queue viewer columns to find out which queue is causing the problem

  • The Message Count also helps to determine the messages captured in the queue. This will help to show if the server is running performance issues and is unable to maintain the workload
  • Because the Queue Viewer does not report the status of the queue in real time, it is periodically refreshed. The user should click on Refresh or wait 30 seconds to check the status of the queue
  • If the user thinks that the mail flow problem is caused by a job stuck in the queue, double click on the queue to see it inside. It not only displays all messages, but also the errors associated with each message (if any)
