As the title shows, I need some help with Outlook. Right now, when I type in a name, the email address pops up, which is great for people I email frequently. However, some of the people I email frequently have changed their email address, but whenever I type in their name, the old address is still the one that appears automatically, and I can't figure out how to make it stop. And I'm hoping somebody can help me. The most annoying part is my boss is one of those people, so I'm constantly sending her emails that she doesn't get, because they go to the wrong place.

I've tried changing my contacts list, but even though their information in their is right, the email is still not showing up right when I go to send something. Every time I try to Google it, it just wants to give me information to change how my name is displayed.

ETA I'm using Outlook 2007.
