Drag/drop msgs from Explorer to Outlook

I know you can highlight multiple messages in Explorer then drag and drop them onto an Outlook folder to move the messages into Outlook.

I want to be able to do this programmatically (for multiple folders and messages). I have tried a multitude of avenues only to achieve unacceptable results.

I feel the only way to do this is to emulate the drag/drop action from Explorer to Outlook via code (VB/VBA please).

Does anyone have any ideas on how this might be done?
