You cannot simultaneously connect to the same POP3 server with different
credentials; only 1 session at a time is allowed.

That said; Outlook in most cases will detect this and will not try to
collect mail from the same server at the same time. Things that can break
this is a too low automatic send/receive interval (with 5 accounts set it to
at least 15min) and virus scanner integration as they will take over the
send/receive session.

I have several email addresses that I aggregate into Outlook 2003. Several
of
them are " addresses. I just added another one, and I input all
the required data (incoming and outgoing server names, email address,
email
account p/w, etc) into Outlook. But when I click on the "Test Account
Settings" button, I get the "Enter Network Password" dialog -- and no
matter
how many times I enter my password there, the dialog won't go away until I
hit "Cancel."

I've verified that the password is correct (works just fine when I access
the Gmail account directly via the browser). All the other settings are
correct. I only aggregate about 5 addresses into Outlook, so it's not as
though I'm overloading the app....

Any suggestions on how to resolve this? Thanks!
