You can transfer email messages or entire conversations from one folder to another:
Drag and drop the item over the desired folder in the left-hand pane.
Select the items, right-click, and select Move. In the Move Message box, select a destination folder, and click OK.
If you are moving a few messages within a conversation, the conversation appears in both places. The Conversation Detail View window shows the new location of the message that was moved.
Note: If you move a message to a folder, you can immediately undo this action by clicking Undo that appears at the top of the page. The message is moved back to its original location.
