Outlook 2003 & Passwords

[OU]

I'm using Outlook 2003. I have 2 sepearate POP accounts
that have about 3 email addresses each. The default email
account and its pop addresses work fine. The 2nd pop
account and its associated email address work, however
Outlook constantly asks for the passwords for each account
eventhough the box is checked to remember password. This
is incredibly frustrating. Especially when you leave
outlook open and every two minutes a window appears asking
for the email password. Hopefully somebody has a
suggestion.

Thanks.
