title: Outlook Add-in: deploying new version does not update in outlook
body: <p>I am currently working on an existing office 365 outlook add-in.
  I'm not using visual studio but eclipse on a mac.
  I simply need to do some debugging to check the response of an api call, so I added my debug code and deployed the add-in on the hosted server.
  Then, from the Office Admin Center  I re-upload the add-in making it available to all users.</p>
  
  <p>The original problem was that the updated version of the add-in did not update straight away in outlook.
  I left it for a day and today outlook was serving the updated add-in but then I had to add some more debugging code and once redeployed the new add-in version again was not served in outlook.
  Thinking it was a caching issue I deleted all the browser cache (Local Storage, Session Storage, Cache Storage).
  Unfortunately since then the Add-in is not loading at all returning an Add-in error:</p>
  
  <pre><code>Uncaught Function ContextActivationManager_getAppContextAsync call failed. ErrorCode is -2, exception: Failed origin check
  
  from outlook-web-16.01.js
  </code></pre>
  
  <p>I tried to re-deploy it updating the version in the manifest but still no success.
  I cannot really afford to waste another day to wait for the new version to kick-in so I was wondering if there is a faster way? Am I doing something wrong in deploying the add-in? Is there a reason why uploading a new version of the add-in it doesn't get served straight away in outlook?</p>
