If you don't want your email to go to outlook express at all, remove the
email account from outlook express (Tools>Accounts>click on the account and
then click remove). Set up your account in Outlook 2000. Open control
panel and open Internet Options>Programs tab and next to the "E-mail"
settings select Microsoft Outlook from the drop down menu.
Hope this helps
