Your Outbox may be corrupt. Delete the Outbox.dbx file and then a new one will be created when you restart OE.

To delete that file navigate to:

C:\Documents and Settings\~ username~\Local Settings\Application Data\Identities\~ id number~\Microsoft\Outlook Express.

Delete the Outbox.dbx file

Alternatively you can locate that Outbox.dbx using Search from the Start Menu.

Note: to locate that file you must have "Show hidden files and folders" enabled.

Windows Explorer > Tools > Folder Options > View > Show hidden files and folders.
