You can do this one of two ways:
1) Uninstall Outlook 2000, remove and set up your user profiles again and then install Outlook 2000.
or
2) IMO mode: if you installed Outlook before setting up user profiles you need to delete the following key in the registry AFTER you log in as a NEW user (to eliminate the profile that is copied to each new user from the original user):
HKEY_CURRENT_USER\Software\Microsoft\Windows Messaging
Subsystem\Profiles\Microsoft Outlook Internet Settings
When you startup Outlook the first time it will recreate that profile for a new user with a new .pst file.
Remember to Always backup your registry before making any changes, in the event of unexpected results.
Let us know if this works for you or not.
