I was using Outlook express and it was working fine, but decided to
start using Outlook. The yahoo mail account is added correctly
including using SMTP port 587 and selecting the "My outgoing server
(SMTP) requires authentication" per the Microsort Office assistance
but it is still not working. HELP!

If you're using port 587, perhaps you don't need to authenticate or perhaps
you should be using port 25 and authenticating. The latter is what I use
with my Yahoo SMTP server.
