title: outlook web-addin not working on desktop client
body: <p>I've developed a web-addin for outlook365. However, for some reason, the add-in stops working on desktop client. It just load the HTML page for the taskpane but not executing the taskpane.js. The add-in still works on web based outlook. I tried to investigate the issue, found that the Office.onReady handler is not called on desktop client. Any idea what could be the cause? </p>
  
  <p>Thanks,
  Peng</p>
