You Should be able to or do you mean something else.
In Windows Live Mail you can drag and email and simply drop it in another folder.
I have just changed my email to a computer with a Windows 7 OS. I was using Outlook express; I have now installed Windows Live Mail. I have imported all my messages. In Outlook Express I could drag a message to any folder. I don't seem to be able to do this now. I can use the "move to" option but it is relatively tedious compared to dragging and dropping.
