title: Microsoft GraphAPI users/delta endpoint returns 404
body: <p>I encountered an odd problem working with the Microsoft GraphAPI beta Delta Query endpoint for users.
  The first 2 requests worked as expected, supplying a "nextLink" in the response.
  Then, the last request (which was supposed to be the last, and according to documentation should have returned a "deltaLink" in the response) fails returning a 404 (non-JSON response).</p>
  
  <p>Is this a known issue with the beta Delta Query?</p>

  <p><b>The response:</b></p>
  
  <p>404 - File or directory not found.
  The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.</p>
