title: Cleaning office add-in cache
body: <p>I have taken over a previously written office add-in with yeoman. I have been changing settings and else but after the initial install to see how far it has gone I believe my outlook client has stored some kind of cache. When I try to install the updated version it still holds the logos and settings for the previous version but when install it on a system which did not have a previous version of it its all good. </p>
  
  <p>Any suggestions help. I have tried deleting my local profile file and recreate it by relaunching outlook but that does not seem to have effect on the whole process.</p>
  
  <p>Thanks </p>
  
  <p>EDIT:</p>
  
  <p>I am talking about the Outlook standalone client.</p>
