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:
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.
Method 6: Repair your Outlook or Outlook Express

 

Repairing your Outlook or Outlook Express may also resolve the problem.

  2. Click the drop-down under Always use this profile, and then select the new profile.
  3. Click OK to close the Mail dialog box.
  4. Use the Import and Export wizard to export your email messages to an Outlook Data File (.pst) from your old Outlook email profile, and then import the Outlook Data File (.pst) to your new Outlook email profile.

    Note     If you are not familiar with the Import and Export feature in Outlook, see the following articles:
    How to export Outlook items to an Outlook Data File (.pst)

A .pst file is a personal-folders file that stores your email messages, contacts, notes, calendar items, and other data. If the .pst file is corrupted, you may not be able to send or receive email messages in Outlook.

To resolve this issue, repair your Outlook personal folder file (.pst) .
Method 10: Clean up email messages that are stuck in your Outbox (Outlook only)

  1. In Outlook, click the Send/Receive tab, and then click Work Offline.

    Note     This stops Outlook from trying to send all email messages.
  2. Select the Outbox. You can now take one of the following actions:
    • Move the message: Move the message to the Drafts folder. You can either drag the message to the Drafts folder or right-click the message, select Move, select Other Folder, and then select the Drafts folder from the list.

      Note This enables you to open the large email message, and remove, resize, and then re-add the attachments before you try to resend the email message again.
    • Delete the message: Right-click the message, and then select Delete.

    Important     If you receive the message "Outlook is transmitting the message," close Outlook, and then wait for it to exit. You may have to use Task Manager in Windows to make sure that the Outlook.exe process is complete. Restart Outlook again, and then repeat step 2.
  3. Click the Send/Receive tab, and then click Work Offline to de-select it.
