Remarks
Setting a will message is a way for clients to notify other subscribed clients about ungraceful disconnects in an appropriate way. In response to the ungraceful disconnect, the service will send the last-will message to the configured telemetry channel. The telemetry channel can be either the default Events endpoint or a custom endpoint defined by IoT hub routing.
