Hi @Nirmal,

so I tried it with your config and my client that subscribed to $dropped/# got the dropped messages. I produced the dropped messages by having an offline client that subscribes to topic "test:

```auto
mqtt sub -t test -q 1 -se 100000 -i sleepyClient

```

Note: disconnect client so he is offline.

So now I add subscriber for dropped topic:

```auto
mqtt sub -t '$dropped/#'

```

Then I publish three messages:

```auto
mqtt pub -t test -q 1 -m "oh no"
mqtt pub -t test -q 1 -m "oh no2"
mqtt pub -t test -q 1 -m "oh no3"

```

And my dropped subscriber gets “oh no2” and “oh no3”, as “oh no” is the one message still queued for the offline client.

I’m still unclear though how you produce dropped messages, I would love to see the Control Center  
notification and the WARN message.

Regarding:

```auto
Also, can we get the dropped messages from the dropped messages topic to Kafka using Kafka-HiveMQ-extension and see that data in Kafka topic?

```

The answer was already given here: [Reprocessing the dropped messages using Kafka Extention](https://community.hivemq.com/t/reprocessing-the-dropped-messages-using-kafka-extention/1402)

Greetings,  
Michael
