I am looking for how to implement the following:
Modify Outlook UI (VSTO, I assume), so the Mailbox view, the navigation pane displays a list of folders, which are not mail folders. They would be folders which represent folders say on our document storage server.
The user should be able to "move" items from say their inbox folder, DRAG AND DROP onto these custom folders mentioned above, then somehow implement code to copy the mail message to the other server.
The requirements are asking to have these custom folders, hopefully inside the Outlook Navigation pane (or at least on left nav ).
My question is what customization concept should I use
My first research (reading only) suggests the usage of a custom task pane, maybe with a tree control. But not sure if I can drag and drop and not sure if I can get the custom task pane to appear in left nav.
Any help would be appreciated. Thank you for your time.
