Expand all | Collapse all

Symptoms

If you are connected to the Internet through MSN, the Microsoft Network, and you attempt to send messages by using an account other than your MSN e-mail account, you may receive an error message that is similar to the following error message:
The connection to the server has failed. Account: '<account name>', Server: '<SMTP server name>', Protocol: SMTP, Port: 25, Secure (SSL): No, Socket Error: 10051, Error Number: 0x800CCC0E

Cause

This behavior can occur because MSN does not allow messages to be sent to another Simple Mail Transfer Protocol (SMTP) server while you are connected to their network.

Resolution

To resolve this behavior, change the SMTP server for your e-mail account to use the MSN SMTP server. To do this:
  1. In Outlook Express, click Accounts on the Tools menu.
  2. Click the Mail tab, select the account that you want to change, and then click the Properties button.
  3. Click the Servers tab.
  4. Under Server Information, delete the entry that is in the Outgoing mail (SMTP) box, and then type smtp.email.msn.com.
  5. Under Outgoing Mail Server, click to select the My server requires authentication check box, and then click the Settings button.
  6. Under Logon Information, click Log on using.
  7. In the Account name box, type you MSN Member ID (everything before the at sign (@) of you MSN e-mail address).
  8. In the Password box, type your MSN account password.
  9. Click to select the Log on using Secure Password Authentication check box.
  10. Click OK to close the Outgoing Mail Server dialog box.
