The space on your hard disk is much bigger, and you can take use of it with MSN Explorer.
To move a message from Hotmail's servers to your local disk
- Select one or more messages in MSN Explorer.
- Click on the Put in Folder... button.
- From the drop-down list, select Archived Mail.
Note: Microsoft has removed this option from MSN Explorer with the introduction of MSN 8. While you cannot save messages locally any more, you can still recover them.
