Autocomplete in To: field has old addresses

[TLXL]

Hello,

I have a problem with my contacts folder in Outlook XP running on Windows
XP. Actually, my contacts folder is fine,... I only have one contacts folder
and no PAB or WAB files. On a new mail item, if I click the To: button my
folder come up fine, but if I start typing in the To: field using the
autocomplete I get incorrect choices for e-mail addresses from some old
version of the contacts folder or something. It's almost like the IE history
of visited addresses. Is it scanning e-mail address from mail items instead
of my contacts folder? Can I set it only pull from the contacts folder?

TIA
