Outlook 2003 has an automatic completion for any email address that you try to type into the To or CC fields. This feature does not pull from the contacts or address book. The problem comes in when you put in a bad address, and then every time you go to type in the email address, the incorrect one appears in the auto complete list.
The easiest way to fix this problem is:
- Start typing in the address that shows up incorrectly.
- Hit the Down arrow key to select the auto completed address.
- Hit the Delete key to delete the auto complete address
