To compact and back up e-mail folders
Select an e-mail folder.
On the File menu, point to Folder, and then click
Compact.
To back up the folder, find the folder file, and then
copy it to a backup folder, floppy disk, or network
drive. Outlook Express e-mail folders have a .dbx
extension (for example, "Sent Items.dbx").
hope this helps
.
More help, please.
