1. Outlook should allow you to view the details of the error by clicking the yellow exclamation-point icon that appears in the lower right-hand corner of Outlook's Window when a send/receive error occurs. Please locate that info and paste the full and exact text here; there's usually an error code listed in those details which can help to pinpoint the problem.
2. If you have any anti-virus or firewall software installed, temporarilly disable it entirely; those programs are known to cause such behaviour in Outlook.

the problem just started a week ago
Judging from the info in your first post It sounds like you've covered all of the normal troubleshooting steps. Did anything else happen around that time that might be related to the problem, or are you noticing any other odd behaviour with the system?
Open a DOS windows and type the following command at the prompt:
telnetyour pop server's name 110
Are you able to hit the POP server that way? If that works, you should get a message beginning with "OK", and a flashing cursor below the message. Type "quit" to end the Telnet session.

Can you give some detail on a couple of things I mentioned earlier please?:
If you have any anti-virus or firewall software installed, temporarilly disable it entirely; those programs are known to cause such behaviour in Outlook.
Did anything else happen around that time that might be related to the problem, or are you noticing any other odd behaviour with the system?
Can you even ping the server from the problematic computer? Open a DOS box again, try both of the ping commands below, and tell us the results:
pingyour pop server's name
ping your pop server's IP address
You should get 4 positive responses from each command if they work.
