I am using Outlook 2002 on WIN2000

When I start an email, and type the first couple of
letter of the recipiant, Outlook brings up a few email
address that start the same and are similar.

This is a major problem. These names are not in my
contacts, but are simply people who I have previously
emailed.

I want to do the following:

1. Either only have this feature work for people who
are in my contact or not at all. I really just want to
turn it off, or delete certian names at will.

Any help with this would be greatly appreciated and
Thanks in advanced.
