Somewhere along the line, Outlook has saved a corrupted e-
mail address for one of my contacts. No matter how many
times I delete the contact and re-enter with correct e-
mail, Outlook remembers the bad version.

Outlook uses some clever little list of all addresses
you've ever typed for a past client somewhere, because
everytime you type a name, it can show you three e-mail
addresses and ask you which one you want. For myself, I
have only one e-mail address listed on my contact file,
but Outlook suggests three (all valid - but not saved in
the contact file)

Where does Outlook store this clever list of all addresses
you've ever e-mailed to in the past, and can I delete
it/reset it so it will start over and correct the bad
addresses?
