When you start Microsoft Outlook 2000 or first connect to your MCI Internet Mail server, you may receive the following error message:
Dial-up networking settings not valid. Please check your password.
Following this message, you may notice that sent mail does not leave your Outbox.


This behavior may result from incorrect settings in the Internet mail account properties. Follow these steps to troubleshoot this behavior:

  1. In Outlook, on the Tools menu, click Accounts.
  2. Click to select your mail account, and then click Properties.
  3. Under the General tab, type the account name and fill in the user information, including your full e-mail address.
  4. Click the Servers tab. In the Outgoing Mail (SMTP) box type the following, in lowercase:
  5. In the Incoming Mail (POP3) box type the following, in lowercase, where xx is a number from 01-99 assigned by MCI:
    NOTE: If your mail server information is different than that which is shown above, use the server name provided by MCI.
  6. Click to select Log On Using and in the Account Name box, type your account name, which is your e-mail name up to, but not including the @ symbol. In the Password box, type your password.
  7. Click OK. Click Close.
Quit and restart Outlook and send a test message
