Using either Window Mail or Live Mail on newly reloaded Vista Home, I get:
Account: 'incoming.verizon.net', Server: 'incoming.verizon.net', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC19
error after a timeout.
Verizon remoted in and said all settings are correct on the mail and can find nothing wrong with account on their end. Everything else seems right on PC. Nothing in the event log. Antivirus not currently installed. Windows firewall off.
I went through the Windows Mail whole registry deletion, directory deletion process and no change.
