If your Windows login doesn't have administrative rights, you will have to log in to Windows with an administrative login, or have someone available who has a Windows login with administrative rights, to add and remove features in Outlook 2003 and Office 2003.
To add or remove features in Outlook 2003, use the Add or Remove Programs application in the Control Panel. To open this application, select Start, Control Panel, Add or Remove Programs if you are using Windows XP. If you are using Windows 2000, select Start, Settings, Control Panel. When the Control Panel opens, start the Control Panel's Add/Remove Programs application. Figure A.9 shows the Add or Remove Programs dialog.
