Azure SB queues sends messages to disabled dead letter queue

Why does my Azure Service Bus queues send messages to the dead letter sub queue when it's not enabled?

Right from the beginning I made sure expired messages wouldn't be moved to the dead letter queue (or so I thought).

In Visual Studio Server Explorer I see this under my queues:

But I also see this:

I can't pull them out as normal so I created a temporary service to handle (get rid of) these and this is what I was able to extract from the brokeredMessage.Properties:

I would like the messages to just stay in the normal queue when they're not completed. So far I've changed MaxDeliveryCount to 1000 but it's not a real solution.

What am I overlooking?

Update Upon reading my own text I realised EnableDeadLetteringOnMessageExpiration has nothing to do with delivery count. Do I have any option to let my messages stay in the normal queue forever? Or do I have to set the MaxDeliveryCount "high enough"?

I had the same issue. Messages will be moved to dead letter if they reached MaxDeliveryCount, even though you disable it. You may want to set MaxDeliveryCount to 0 or int.MaxValue to stop deadlettering.

NOTE: This information is not documented anywhere. I figured that out by finding people who work on ServiceBus Queue specifically.
