Outlook Live lets you use a Web browser to access your Exchange mailbox from any computer with an Internet connection. In fact, you can do many of the same things you can do with Outlook, for example, read and send e-mail messages, organize contacts, create tasks, and schedule appointments.
Outlook Live isn't the only way to access your Exchange mailbox. You can also access your mailbox from Outlook 2007, from a mobile phone that supports Exchange ActiveSync, and from any e-mail program that supports the POP or IMAP protocols.
