i recently upgraded from outlook 2000 to 2003. i'm now getting the following
error when i'm done downloading roughly 1/2 to 3/4 of my email:

Task 'mail.mydomain.com - Receiving' reported error (0x800CCC90) : 'Your
incoming (POP3) e-mail server has reported an internal error. If you
continue to receive this message, contact your server administrator or
Internet service provider (ISP).  The server responded: .'

there's never anything in the "The server responded..." section.  once it
dies, it seems to forget that it's already downloaded a bunch of the emails
before and starts all over again.  to fix the error, i have to login to my
email account via the web interface and then manually delete most of the
spam and other emails. once that's done, i'm able to pick up my email
throughout the day. when i come back in the next morning and a bunch of spam
has accumulated in my inbox, i get the same error and have to manually clean
things up again.

i've already checked with the isp and there's nothing wrong on that end.
i've also applied all the service packs. what can i do to fix this?

tks
