Note    This article applies to the Internet Mail Only configuration of Outlook 2000. If you're not sure which configuration of Outlook you have, on the Help menu, click About Microsoft Outlook to check.

When you start Outlook or first connect to your MCI Internet e-mail server, you might receive the following error message: "Dial-up networking settings not valid. Please check your password."

After you receive this message, sent messages might not leave your Outbox.

This problem might be caused by incorrect settings in the Internet e-mail account properties. Try the following procedure:

Check your e-mail server settings

1. In Outlook, on the Tools menu, click Accounts.
2. In the list of accounts, click your MCI e-mail account, and then click Properties.
3. Click the Servers tab, and then check the entries in the Incoming mail (Pop3) and Outgoing mail (SMTP) boxes. They should be in lower case letters and should match the table below.
   

   Incoming mail (Pop3)	Outgoing mail (SMTP)
   mailxx.mci2000.com   (where xx is the number you were assigned with your MCI e-mail account)	mailrelay.mci2000.com

    Note    If your mail server entries are completely different than listed above, carefully check the server names against what you were provided by MCI. They should match exactly and be in lower case letters.
   

4. In the Account name box, check the accuracy of the part of your e-mail name before the @ sign.
5. In the Password box, type your password. Remember, passwords are case sensitive, so you must use the same upper and lower case letters that you entered when you set up your account.
6. Click OK, and then click Close.
