Outlook has two "screens" -- the Explorer window to show folders and their
contents and the Inspector window to show an individual item. Your
description applies to the Explorer window.
In versions before Outlook 2007, Outlook does not directly expose the
right-click context menu in its CommandBars collection. Richard Kagerer has
posted a code sample at
http://www.outlookcode.com/codedetail.aspx?id=314
that shows how you might trick Outlook into exposing the context menu through
Explorer.CommandBars. The C++ sample add-in at
http://www.codeproject.com/atl/outlook2k3addin.asp also shows a technique for
working with the context menu. Both that and the Kagerer sample, though, use
unsupported techniques.
Outlook 2007 provides Application-level events for the most commonly used
context menus. Outlook MVP Eric Legault provides an introduction at
