A. Microsoft's Internet E-mail clients (both Internet Mail under IE3 and Outlook Express under IE4) waste a large amount of disk space due to the method used to store mail. The reason behind this is to improve performance, however if you do want to reclaim some of the lost space perform the following:

  1. Select one of the folders, e.g. Inbox, Outbox, Sent Items
  2. Select Folder from the File menu and select "Compact all Folders"

Also set-up Outlook to automatically delete the "Deleted Items" folder contents

  1. Select Options from the Tools menu
  2. Select the General tab
  3. Check the "Empty messages from the 'Deleted Items' folder on exit" and click OK
