Gets the UID collection of the messages being copied/moved from the current folder.
The collection of UIDs of the messages being copied/moved from the current folder, or a null reference (Nothing in Visual Basic) if UIDPLUS extension is not supported or the messages were not copied or moved.
After copying or moving messages, this property contains the UIDs of the copied/moved messages in the source folder (which is the currently selected folder). For instance, if the messages with UIDs 567 and 680 were moved from "Inbox" folder into "Sent" folder and were assigned UID 13 and 14 in "Sent" folder, this property will return the collection containing UIDs 567 and 680.
UploadMessage method sets this property to null.
