Is this a "learned" process for Outlook?

I finally got my address book back up & running but now it seems to lack this feature eexcept for the most recent e-mails I've sent. It recognizes these but no others in the address book.

i did try both turning on & off along with restarting Outlook the
"Suggest names while completing To, Cc, and Bcc" feature in the advanced e-mail options menu. didn't help.

any ideas??

thanks ,Evan
