Outlook Repeatedly Requests Username & Password

[sethdashper]

I use Outlook (2003 SP2) to collect mail from a couple of POP3
accounts - Yahoo! and my ISP account. All has been running smoothly for
months...until now.

Although Username and Pass are 'remembered' (and are correct), every
time Outlook performs a send/receive it requests username and password.
Ticking 'save this password...' on the pop-up makes no difference. The
user and pass are prefilled on this pop-up, but the annoying window
often appears more than once per send/receive.

There's no other resource accessing the same accounts, the user/pass
are correct, and amending the registry as per this Microsoft Knowledge
Base made no difference (http://support.microsoft.com/?id=290684).

Any advice gratefully received...

Similar problem here...

The HKEY_CURRENT_USER\Software\Microsoft\Protected Storage System Provider
solution did not change a thing. I think the problem is still related to
that though because \Protected Storage System Provider is now empty. The
key that was removed (as described in the KB solution) did not regenerate
after I re-installed Outlook.

I even performed a complete OfficeXP re-install and no change.

My problem is somewhat different to yours though in that PW prompt only
happens at the beginning of Outlook sessions. Once Outlook is open the PW
is locked in. Closing and re-opening brings another password prompt.

Question for the MS techies here:

Is the \Protected Storage System Provider the only place passwords are
remembered?
Is the
