We are consuming messages from Azure ServiceBus topic subscription. We don't own or manage the topic, we are just consumers. We would like to access previously consumed messages.
I did not found a way using API. I don't know if it is possible maybe for owner of topic.
Is it possible somehow seek backward / rewind topic subscription position and replay previous messages that are maybe still in topic ?
A topic subscription is basically like a queue, once a message is completed it's gone. It's not like Event Hub where you can choose what event to start from in a partition.
Thanks @juunas and I do agree that this is a queue based but not a stream one. If a message is completed in Queue or Topic's Subscription it cannot be retrieved back:
It can be completed by below way or by any programmatical way, it cannot be retrieved back:
But, from now on if you want to maintain the messages, then you can use Logic apps as an alternative, it triggers whenever a message arrives, and you can store it in a file or to another service bus topic or queue.
