Can anyone please shed some light on how to add a menu
item to the popup menu that displays when you right click
on an email message in the Inbox of MS Outlook?  I would
prefer C# examples.

If you could also provide an example on how to hook up the
menu click event that would be great (altough this is not
critical, I can probably figure it out given how to add
the menu item).

Thanks in advance.

Outlook does not expose the right-click context menu in its CommandBars collection. AFAIK, the only time you'll see a new right-click command is when the item is using a custom form with one or more custom actions.
