Check your e-mail account settings

1. On the Tools menu, click Accounts.
2. Select the e-mail account, and then click Properties.
3. On the Servers, Connection, and Advanced tabs, check the settings against those given to you by your Internet service provider (ISP).

   If your settings match the ISP information, contact your ISP to verify that you have the correct information and that the ISP servers are operating correctly. Also, make sure your ISP server supports PPP, SMTP, and POP3 or IMAP protocols.
