title: Registering custom url protocl handler that Outlook recognizes?
body: <p>Good morning,</p>
  
  <p>I've successfully created a little app that registers itself under a custom uri protocol ('irma:') following the msdn entry at <a href="http://msdn.microsoft.com/en-us/library/aa767914(VS.85).aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/aa767914(VS.85).aspx</a></p>
  
  <p>This works perfectly fine when opening such a link manually via the shell/cmd etc, but when sending out links like that, outlook does not recognize those 'automatically' on the clients that registry key is set. Do I have to do something extra to let outlook handle such custom uri's or is it possible at all?</p>
  
  <p>Cheers and thanks,
  -j</p>
