title: Excel for Mac JS Add-in HTTP Request Timeout
body: <p>I'm working on an Excel js add-in. The add-in has multiple rest api calls using ajax. One in particular can take some time to respond (in this case over 10 minutes). It is working properly in Excel Online - the response is received and displayed. Excel for Mac appears to have a timeout (or something) affecting the request after 1 minute. It's returning a status code 0 and our server is throwing a 499 (client cancelled request).</p>
  
  <p>Is there a timeout in Office for Mac and, if so, is there a way to change it? Adding a timeout field to the ajax request isn't working.</p>
