Can't send email in Outlook 2002

I’m having a problem connecting to our incoming mail server using Outlook 2002. If I try to test my account settings in outlook, it can’t find the incoming mail server (POP3).

When I try to send out an email, I get a message saying that
Task ‘Jamison Wayson email - Sending and Receiving’ reported error (0x800CCC0D) : ‘Unable to find the e-mail server. Please verify the server information in your account properties.’

Any ideas?
