A. Outlook Express stores the contents of each folder (e.g, Inbox, Outbox) in a separate file. To work around this problem, you need to delete the file that is associated with the Outlook Express Outbox. Perform the following steps:

  1. Close Outlook Express.
  2. Start Windows Explorer (Start, Run, Explorer or Win+E).
  3. Go to your profile area (e.g., C:\Documents and Settings\savillj\).
  4. Within your profile, go to the folder Local Settings\Application Data\Identities\\{\[very long number\]\}\Microsoft\Outlook Express.
  5. Find file Outbox.dbx and delete it.
  6. Start Outlook Express (msimn.exe).
  7. The system will create a new Outbox.dbx, and the Outbox will be empty.
