Resolution

To resolve this issue, use one or more of the following methods. After you complete each method, send yourself a test email message to make sure that you can send and receive messages without receiving an error message. If you continue to receive errors, try the next method.
 

Method 1: Make sure that you are connected to the Internet

To do this, follow these steps:

  1. Start an Internet browser. For example, start Internet Explorer.

  2. Type one of the following addresses in the address bar, and then press Enter.

    • http://www.microsoft.com

    • http://www.msn.com

    If you continue to experience Internet connectivity issues, see troubleshoot network connectivity problems in Internet Explorer.

Method 2: Make sure that your Outlook email account settings are correct

See the following articles in the Microsoft Knowledge Base, as appropriate, to check your Outlook email account settings:

How to set up an Internet email account in Outlook 2013 or 2016

How to set up an Internet email account in Outlook 2010

How to set up Internet email accounts in Outlook 2007 or 2003

Method 3: Delete suspicious email messages from your mailbox

Suspicious email messages may block your receiving error message in Outlook. If you have any suspicious email message, delete them by using one of the following methods:

  • Access your mailbox by using your ISP's web-based email program. Then, delete the email messages.

  • Contact your ISP and ask them to delete the email messages.

Method 4: Check your antivirus manufacturer's website for additional suggestions

If your antivirus software includes an email-scanning feature, you may have to perform additional configuration tasks to use Outlook or Outlook Express together with the antivirus software. For example, you may have to configure the Norton AntiVirus Office plug-in to work with Outlook.

For more information about how to use Outlook together with your antivirus software, go to one of the following websites, as appropriate for the antivirus software that you have installed:

  • Symantec

  • McAfee

  • Trend Micro

  • Panda

Method 5: Configure your firewall software to enable Outlook to access the Internet

Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.

Configure your firewall software to enable the following files to access the Internet:

  • Outlook.exe (for Outlook)

  • Msimn.exe (for Outlook Express)

By default, port 25 is for outgoing access, and port 110 is for incoming access. If you are not sure about the ports, contact your ISP or system administrator.

More information for McAfee Personal Firewall and Norton Personal Firewall (Symantec)

Go to the McAfee website for instructions on how to configure McAfee Personal Firewall.

Or, you can remove and reinstall McAfee Personal Firewall. This reinstallation process will make sure that Outlook and Outlook Express have Internet access, because the process re-creates the program signature file that is used by the firewall.

If you are running Norton Personal Firewall 2002, Norton Internet Security, or Norton SystemWorks software by Symantec, contact Symantec product support for upgrade or reconfiguration instructions to resolve your problem.

Which network is used for email?

SMTP and Email There are three common protocols used to deliver email over the Internet: the Simple Mail Transfer Protocol (SMTP), the Post Office Protocol (POP), and the Internet Message Access Protocol (IMAP). All three use TCP, and the last two are used for accessing electronic mailboxes.

How are e

' Individual messages are routed through multiple servers before they reach the recipient's email server, similar to the way a traditional letter might travel through several post offices before it reaches its recipient's mailbox.

What is POP3 and IMAP?

Full Form. POP3 is an abbreviation for Post Office Protocol 3. IMAP is an abbreviation for Internet Message Access Protocol. Introduction. The POP is an Internet standard protocol on the application layer that the local email clients use for retrieving emails from any remote server over the TCP/IP connection.

What is the use of POP3 and SMTP?

SMTP sends the email from the sender's device to the receiver's mailbox, and POP3 retrieves and organizes emails from the receiver's mail server to the receiver's computer. SMTP functions between the sender's and receiver's mail servers, and POP3 functions between the receiver and the receiver's mail server.
