You can't fully quit Outlook when you use a COM Add-in in Outlook 2002

You create an Outlook COM Add-in, but Outlook does not fully quit when you click Exit on the File menu.
This typically happens when you use an Explorer or Inspector object variable and it is not properly released by the COM Add-in.

When the OnBeginShutdown event fires in the COM Add-in, the forms (Inspectors) and folder windows (Explorers) have already been closed. Therefore it is impossible to set these objects to Nothing using the COM Add-in's OnDisconnect or OnBeginShutdown events, since the object variables are no longer valid, and will generate errors if used.
Implement the Close event for the Explorer or Inspector object, and then set the corresponding object variable to Nothing at the end of that event.
