title: Prevent group rename in Outlook 2013 in VSTO Addin
body: <p>I am developing a VSTO addin in Visual Studio 2013 for Outlook 2013.  I add my own group to a few of the ribbons, such as the Home tab in Explorer view.<br>
  I would like to prevent anyone from renaming my group.  Users can use the Customize Ribbon feature in Outlook to manage groups and commands and I can easily rename, move, or remove the group by customizing it.
  Is there a way I can attach to an event and prevent the user from renaming my group (I would prefer to be able to prevent them from removing/hiding my group too).
  I have looked through the Outlook 2013 Object Model list and I cannot find any relevant events to attach to.  I don't see any Group objects or anything that looks relevant.</p>
