annoying pop up asking for network settings

[Catchin'' On]

Hello,

I have my Outlook set-up to bring in emails from about 10 email addresses
and to place them into a certain forlder when they arrive. I am experiencing
a very annoying problem that happens very randomly. I will be typing an
email and a box pops up that wants me to enter the user name and password and
it says "Enter Network Password". I have the save password checked and under
"more settings" I have in the email accounts set-up i have my smtp to log in
under my user name and password with the password saved. It happens for many
of the accounts if not all, and very randomly.

Also, when click send receive all, it will bring in some accounts, but the
if i go the send receive for only that one account and download the inbox,
sometinmes there were messages that were not downloaded when i clicked send
receive all.

Sorry if this is confusing, but if anyone can help please do... This pop=up
is really annoying as it will pop-up when i am typing a message and screws me
up a lot.

Thanks to anyonw...
