1. Where are the details of these old accounts retained? Presumably somewhere in the registry but where and how can I delete them for good?
The registry contains no files.
It "points to files".
Deletion will require searching likely places:
C:\Documents & Settings\(old and new)Usernames\Application Data\Outlook\?
if it exists there like other programs do (but probably doesn't since its a "special" microsoft app)
please note: I use t-bird primarily do to it's accessibility regarding folders/files/configurations.
Something I found Outlook and Outlook Express lack.
I haven't got the exact answer, presently haven't got winXP loaded, but feel it safe to
point you in the direction of locating them. Once found, generally deletion of files, not the folder itself,
is the way to approach it. Try one or two first, and determine effects. If problems occur, restore the
file, and chock it up to experience. Try searching for the files once you know a filename and/or
extension ... using the search button in your start menu?
