title: Handling attachment events in an outlook add-in
body: <p>Is anyone aware of a technique I could use to override someone opening an email attachment within an outlook add-in? </p>
  
  <p>Essentially what I'm being asked to do, is for certain attachments, to change the behavior so instead of opening the attachment the user is redirected to a webpage.</p>
  
  <p>I can hook into the attachment context menu with <a href="http://msdn.microsoft.com/en-us/library/bb175107%28v=office.12%29.aspx" rel="nofollow"><code>Application.AttachmentContextMenuDisplay</code></a> however that is not fired if the user simply double clicks on an email attachment. </p>
  
  <p>Environment used is VS2010, c#, and outlook 2007/2010.</p>
