If “Error 0x800ccc0f – Connection To the Server Was Interrupted” appears when attempting to send or receive an e-mail message, the enabled anti-virus protection utility most likely caused the error.

4- Select Properties from the Menu.
5- Click the Security tab then switch off the Microsoft Windows Firewall.
After disabling the Firewall, manually add the incoming POP server name (mail.example.com) and the outgoing SMTP server name (mail.example.com) to the E-mail Accounts Dialog Box in Outlook.

2- Click E-mail Accounts on the Tools Menu.
