What is a Microsoft Exchange account?

Some features in Outlook require you to use a Microsoft Exchange account. Exchange is an e-mail-based collaborative communications server for businesses. Licenses for Exchange can be purchased from Microsoft and its resellers. Exchange Services Provide Online Outlook Support and Email Support for the Outlook.
If your organization uses Exchange, but you do not know whether you have an account or how to use it, you must contact your organization's Help desk or network administrator for assistance.
Home users typically do not have an Exchange account; instead they use a POP3 e-mail account with an Internet service provider (ISP) (ISP: A business that provides access to the Internet for such things as electronic mail, chat rooms, or use of the World Wide Web. Some ISPs are multinational, offering access in many locations, while others are limited to a specific region.) or use a Web-based e-mail service, such as Windows Live Mail. If you use a POP3 (POP3: A common protocol that is used to retrieve e-mail messages from an Internet e-mail server.) e-mail account, your ISP can provide you with your specific account information. People without Exchange accounts cannot use the features in Outlook that require Exchange.
