If you try to publish a message using publish_message_to_iot_core
then it will return an error if the queue is full. This is the only way to know the status of the outbound MQTT queue, which is what I'm assuming you're asking about.
Cheers,

Thanks! and this error where appears? in the log of the component that sends the message?
