Move Messages via Drag and Drop in Mac OS X Mail
To file emails by dragging and dropping them in Mac OS X Mail:
- Highlight one or more messages in Mac OS X Mail.
- Click and drag the message(s) while holding down the mouse button to any destination mailbox in the mailboxes pane.
- Release the mouse button to drop the message(s) there.
So far, so good and well-known. But what happens when the mailboxes pane is not open?
Spring-Load the Folder
As soon as you start dragging messages around, Mac OS X Mail will automatically show it. When your drag and drop action has finished, Mac OS X Mail hides the mailboxes pane again.
