Fix SMTP Server error in Email

An SMTP Server error (such as number 0x800CCC79) can be caused by an error in the setup in your email program (Outlook Express or Outlook) for the outgoing (SMTP) mail server. A mistake in the username, password, server address, or server authentication can produce this error message when attempting to send an email. To correct this error, you need to know from your email provider what type of authentication, if any, is required by their mail server.

To verify your existing SMTP server settings:

    1. Open your email program (Outlook Express, Outlook, Eudora or Windows Mail)
    2. Click "Accounts" in the "Tools" menu
    3. Click on your email account then click "Properties" button
    4. Click "General" tab
    5. Ensure that the "E-mail address" is your valid address for this account
    6. Click "Servers" tab
    7. Verify your account name is complete and its password is correct for this account
    8. Un-check "Log on using Secure Password Authentication" (unless specified otherwise by your email provider)
    9. Check or uncheck (as directed by your email provider )"My Server requires authentication". If authentication is required by your provider, click the Settings button. On the "Logon Info" screen, select as specified by your email provider, either
      • "Use same settings as my incoming mail server"; or

      • "Log on using" and enter the specified Account Name and Password.

    10. Delete messages in the "Outbox" folder and send your email message again.

To setup or verify all your email settings, follow the instructions at Setup Email in Outlook Express.
