Check the connection to your Internet service provider
Try these steps as appropriate:
Establish the connection to your Internet service provider (ISP) before attempting to view or download messages.
If you use a modem, check your connection settings. To check your settings:
If you are using Windows 98, on the desktop, double-click My Computer, double-click Dial-up Networking, and then double-click the icon that represents your ISP.
If you are using Windows 2000 or Windows Millennium Edition, click Start, point to Settings, and then click Network and Dial-up Connections or Dial-up Networking.
If you are using Windows XP, click Start, click Control Panel, click Network and Internet Connections, click Internet Options, and then click the Connections tab.
If you use a local area network (LAN) or proxy server connections, contact your network administrator.
For help with your dial-up networking connection, see the dial-up networking (or dial-up connection) section of Windows Help.
If you suspect that there is something wrong with your modem, see information on modems in Windows Help.
