How to delete/clear active/dead-letter messages from Azure Service Bus Queue?

Question

Is there anyway to delete/clear either the active/dead-letter messages from Azure Service Bus Queue in Azure portal? Currently we've sent a couple of messages to our queue while both the active and some dead-letter messages holds up there for nothing, and our service bus subscriber didn't trigger somehow, so we'd like to delete these messages to make our queue clean again. In order to wait until service bus drop these messages after expiration period, could we manually remove them ourselves?

Answer 1

There is a way in the portal .

1. Navigate to the topic / subscription

2. Set the mode to Receive

3. Then Click on Receive Messages and in the pop-up set the option as ReceiveAndDelete

4. Repeat the process until the DLQ is clear

Note : Observe the difference in the messages count between step 2 and step 4 ( shows the messages are deleted ) .
