I have Outlook 2000 SR-1, and use Windows XP Professional, Version 2002, Service Pack 2 (to the extent it is relevant). When I go to address an email by scrolling down the list of contacts that show up by clicking on the email "to" button, only some of my contacts come through, despite the fact that all of my contacts contain email addresses. I have checked the Microsoft website, and their fix on this (OL 2000 (CW)/Q197907) for Outlook 2000 is limited to Outlook installed with the "corporate or workgroup" option, which mine is not. I was unable to find any additional help for this version of Outlook and would greatly appreciate any insights. Thank you very much.
