Windows Live Hotmail is one of the largest providers of free, web-based e‑mail. This is a helpful service to use when you have more than one computer, travel frequently and use various computers, or don't own a computer at all. Messages are stored in a central location—rather than on your computer—so they're always available, no matter where you are. With Windows Live Hotmail, you can send and receive e‑mail messages from any computer that has a working Internet connection and a supported web browser.
Windows Live Hotmail is web-based, so you must have an Internet connection to send and receive messages. Hotmail normally runs in Internet Explorer or another supported web browser, and keeps your messages stored on a Hotmail server. But you do have the option of checking your Hotmail messages in Windows Live Mail, which stores messages on your PC. (You can also check your Hotmail in Microsoft Office Outlook. For information on how to do that, see One place for all your mail: Read your Hotmail in Outlook.)
Windows Live Mail is an e‑mail program that you install on your computer. It allows you to send and receive messages from one e‑mail account or from multiple accounts with different e‑mail services, including Hotmail.
With Windows Live Mail, messages are stored on your PC, allowing you to access, read, and compose e‑mail messages even when you're not connected to the Internet. Once you connect, Windows Live Mail will send and receive messages and update your accounts.
Windows Live Mail is designed to work with most popular e‑mail services, as well as e‑mail services from even the smallest ISPs. All that's required is for the e‑mail provider to offer Post Office Protocol (POP3) or Internet Message Access Protocol (IMAP) access. (Some popular services, such as Yahoo! Mail, require a premium subscription for POP3 access.)
