Ain't that the truth!

Is there any chance at all that:
  - you could install Thunderbird or Eudora and try connecting with that 
  - the ISP has changed their POP server, so it now advertises a POP 
option that
    Outlook can/will not support? or even changed the POP server 
configuration so
    that it doesn't support broken clients like Outlook*?
  - you could run a protocol analyser or packet sniffer on the firewall 
    investigate the problem at the wire level? This will often point out 
one of
    those "duh!" problems such as looking up the wrong host name...

I don't know about POP, but IMAP support in Outlook is broken, because 
it sends IMAP messages that aren't correctly formatted during the 
session initialisation, and expects headers from the server that are 
broken the same way.
