So, you are a savvy Exchange administrator with a proactive monitoring tool and you are notified that your Submission queue on one of your Exchange servers has a high quantity of messages in the queue.
What do you do?
First, you will want to check the submission queue
- Open the Exchange Management Console and click Toolbox
- Then Choose Queue Viewer
- Notice there are 247 messages in the submission queue in this case, but there could be any quantity here.
- Double-click on the submission queue and notice that the messages likely are similar with the following detail:
From Address: <>
Status: Retry
Last Error: 420 4.2.0 RESOLVER.ADR.Ambiguous; ambiguous address
Cause
The submission queue can become backlogged for several reasons. For example, there could be a message in the queue with a bad header or alerting was enabled for a third-party application that caused an arbitrary loop. In either case, take the time to research and track down the root cause.
Resolution options
- Go to Start, Control Panel, Administrative Tools
- Double-click Services
- Restart the Microsoft Exchange Transport Service
If this doesn’t resolve your issue
- Open Exchange Management Shell
- Type Get-Message -Filter {FromAddress -eq “<>”} -Server hubtransportserver | Remove-Message and press Enter
- Choose A to select Yes to All
looool 🙂
so if there is a problem you just delete those messages from the queue and thats it :)))))
