title: c# outlook addin - add custom flags or icons for emails
body: <p>currently we can add some red flags to email. And after that, we can those flag icons to appear while listing of emails.  </p>
  
  <p>I want the similar thing to happen but I want a custom icon. </p>
  
  <p>Is that possible.  </p>
  
  <p>Also it became really difficult to get support on c# outlook addin.  Where can I get proper support ?</p>
  
  <p>More details if you want:  </p>
  
  <p>I have already built an addin with forms and some actions etc. In outlook we can see list of emails. After clicking an email, we can click some buttons(like 'push to server'). Once clicked, the email will be stored in server and also will be moved to another folder.  But we also need another functionality.  We should be able to see some icons (like flags etc) in the email (or for each mailitem in the list of items like flags) that says whether it is already pushed to server.  </p>
  
  <p>Regarding what I have tried, I donno where to start, there is no online documentation for custom icons or flags(have been trying from days). To say clearly what I tried, in vs2013, Outlook.OlFlagIcon. - then vs2013 shows list of available flags, but there is no method like add.  </p>
