Removes the assurance that an item will be available offline.  In addition, if the item is no longer pinned for any reason and if it has no unsynchronized local changes, it is automatically deleted from the Offline Files cache.  To monitor progress, implement a WMI event sink to receive OnProgress notifications.  The Message parameter contains a text string encoded with the following colon-delimited format: 

    :::[] 

where: 

     
        The type of progress notification.  One of the following: 
            0 = Begin      - Sent once at start of the operation. 
            1 = End        - Sent once at the end of the operation. 
            2 = ItemBegin  - Sent at the start of processing each item. 
            3 = ItemResult - Sent at the end of processing each item. 

     
        Unsigned integer HRESULT.  0 = Success.
