RE: VSTO 2005 Beta 2 Outlook Addin: How to create a context menu?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I would not recommend developing a solution around a context menu if you need
it to be 100% reliable. There are scenarios (such as the one you've found)
where the event does not fire thus your code to add you context menu does not
fire. The sample code checks to see if the mail item's subject contains
specific text and if so add the context menu. You should be able to just
strip this out and add it for all items. Also we cast the selectedItem as a
MailItem. If I you want to add it to other objects just try to type cast it
to other objects such as a contact or calendar item.
