Have you ever changed the address for someone in Outlook and, after awhile, it goes back to the old address? This has been a very weird problem for me that is only happening on my work computer, not my home computer. Everyone thinks I am an old bat, but I am not stupid. Our staff has changed. So I will remove the people who are gone. Then a few days later I send an e-mail to the staff and the old people get it, too. Yes, I had already gone into the group contact list and deleted people. And added people, who are then not there. Do you think I need to reload Outlook? Which I think will involve reloading the entire Microsoft Office package, right? :dubious: ---

When you have the address problem, does anything else revert to the way it was on an earlier date? Do old emails reappear in your Inbox? Do you synchronize your Outlook addresses with a PDA or another program? Are you using an Exchange server or a separate .pst file? If the latter, where is it located? (You can find out by right-clicking the **Outlook Today** or **Personal Folders** heading in the Folder List, hitting **Properties** , then the **Advanced** button). Do you use a roaming profile or Offline Files? (You may have to ask your network administrator.) What version of Outlook are you using?
