They're stored in an .nk2 file on your system. When you see an address you don't want to use any more, simply use the arrow keys to highlight it, then press Delete.

I have some erroneous spellings of Outlook addresses. When the automatic
"fill in" for names begins, as I start typing a regularly used email address,
the wrong ones come up with the right ones. Where are they stored so I can
delete these erroneous addresses and not get automatic bad addresses coming
up with good ones in Microsoft Outlook?
