My brother claims on his old computer with Outlook 2000 when you started
typing an email address a drop down list would appear wth a list of previous
email addresses used and you could select which one you wanted instead of
having to type the whole email add.
On his new computer he said that drop down list doesn't appear.
Operating system WIN XP.
I do not use Outlook and am unfamiliar with it.

How can he turn that autofill feature on??

Thank you
