Folder Context menu in Outlook

[NotAMail]

Hello,

I have develop an Outlook COM Add-in with C#.
This add-in use the Outlook Object Model and add a new menu in the Folder
Context Menu command bar.

The problem is when the current folder is for example "Inbox", and I click
right on another folder, for example "MyFolder",
I'm not able to retrieve the MAPIFolder of "MyFolder".

Anybody have an idea?

Thank you
