body: <p>I want to know that is there any message inqueue limit define for service bus queue or topic.</p>
  
  <p>Let say I have create a device on azure iot hub .Now I am sending c2d message to this device. If there is no receiver available for this device. Then it has capability to save 50 message in queue. After this limit . It will discard all the c2d message send to it.</p>
