I have created a service bus queue in Azure and it works well. And if the message is not getting delivered within default try (10 times), it is correctly moving the message to the dead letter queue.
Now, I would like to resubmit this message from the dead letter queue back to the queue where it originated and see if it works again. I have tried the same using service bus explorer. But it gets moved to the dead letter queue immediately.
Is it possible to do the same, and if so how?
The Service Bus Explorer tool always creates a clone of the original message when you repair and resubmit a message from the deadletter queue. It could not be any different as by default Service Bus messaging does not provide any message repair and resubmit mechanism. I suggest you to investigate why your message gets ends up in the deadletter queue as well as its clone when you resubmit it. Hope this helps!
