I am having the exact same problem. I have deleted the accounts and
re-installed them to no avail. This all started after I installed Vista and
WLOC. I configured my accounts on my wife's computer (XP) and my email works
fine. When I setup my accounts on my vista machine I push the button to test
settings and it passes all tests and I finish the setup and it goes right
back to the same error message. I have been searching high and low for a
fix, but nothing yet.

I'm just about to expose how little I know about Outlook. MS Office Basic
2003 was clean installed on a new PC running XP a few weeks ago. I correctly
opened a mail account for myself in Outlook (Internet Only) linking properly
for 'send and receive' with my cable ISP. Everything ran fine and I
gradually customized my Outlook. I have a simple at home setup with a
mini-network involving my wife's desktop and a Laptop.

Now suddenly out of the blue I don't receive any email any more. When I open
Outlook, which is set to open in Inbox and automatically download new mail,
I get a dialog, with the heading Enter Network Password - the Server, User
Name and Password already (correctly) filled in. The box tells me to" type
your user name and password." An error box, when it appears, says that my
ISP has rejected my identifying data (which, Password or User Name, I don't
know). I do all this after erasing what's already there, with no effect.

This is what I've done. I double checked my account settings and everything
was alright - I closed that one and opened a new account anyway. I
successfully sent a test email to my wife - whose account with the same
carrier is working perfectly. I ran Detect and Repair in Outlook - MS Office
was reinstalled from cab files. I still don't receive email via Outlook and
the request for User Name and Password continues to appear, even when I am
in another application. I have cable High Speed Internet which is "always
on."

Web Mail works perfectly. When they arrive, because of the new computer, I'm
going to upgrade to Vista and MS Office Basic 2007. Before that happens I
need to solve this delivery problem . I'd surely appreciate some help.
