Unable to reach POP3 Servers from Outlook 2003

I've reloaded all software trying to resolve this. Without any obvious cause
Outlook 2003 quit accessing defined e-mail accounts inbound and outbound for
POP3 (only use POP3). The WAN connection shows TCP/IP but will not allow
uninstall and install may not be working due to an unsigned driver. I've
walked through all Outlook settings with the ISP. The e-mail service works
fine through web mail. I did find the Microsoft IPV6 driver loaded.
Outlook's Send/Receive Progress initially shows 0x8004210A and 0x8004210B
errors. The BellSouth/AT&T tool confirms the e-mail addresses Outlook is
using are sending and receiving but Outlook continues to have problems.

I have no problems using IE, or any other software which access the Internet.

All suggestions are warmly appreciated.

Has OL ever run, or have you upgraded to OL2003?
Try uninstalling any anti virus app that is intergrated into OL
