cannot receive email at secondary address
 

In Outlook 2002, I cannot receive mail at my secondary address. I followed
the install protocol for POP and tested okay at the end. Now, each time I do
a send/receive, a "Enter Network Password" box pops up with my server, user
name and password asking OK or Cancel. Responding to this does nothing but
make the box go away. Email comes and goes regularly at my primary.
