The documentation for SpamKiller says that, for the toolbar to be visible in
Outlook, Outlook must be configured in Corporate/Workgroup mode and the
first email account added to SpamKiller must be an Exchange account. (The
docs say "MAPI account" but Exchange is implied.)
FWIW, after an hour, I gave up trying to get it to work on Outlook 2003.
