Everything worked properly till yesterday but today when I opened MS Outlook email application and tried to send/receive email message, get an error message:

Task 'server name - Sending and Receiving' reported error (0x800ccc0f): 'The connection to the server was interrupted. …..

SYMPTOMS

When you try to send or receive an e-mail message in Outlook 2002, you may receive an error message similar to the following:

CAUSE

This problem may occur if you have an antivirus e-mail protection utility enabled, which checks the mail as it comes in from your Post Office Protocol (POP) server.

To resolve this problem, disable the antivirus e-mail protection utility as well as the Windows Firewall, to disable the Windows Firewall, follow these steps:

1. Open the Control Panel (Start > Control Panel)
2. Open Network Connection
3. Right click on the internet connection you’re using (LAN, or Wireless, or GreenNet Dial-up)
4. From the menu select ‘Properties’
5. Go to the ‘Security’ tab, and switch off the Firewall.

Then, if you haven’t already done so you need to manually add the incoming POP server name (pop.gn.apc.org) and the outgoing SMTP server name (smtp.gn.apc.org) in the E-mail Accounts dialog box in Outlook. To manually add the POP server setting, follow these steps:

1. Start Outlook.
2. On the Tools menu, click E-mail Accounts.
3. Click View or change existing e-mail accounts, and then click Next.

SYMPTOMS
