Exchange Online Service Description
Topic Last Modified: 2013-05-09
Microsoft Exchange Online is a hosted messaging solution that delivers the capabilities of Microsoft Exchange Server as a cloud-based service. It gives users single sign-on access to email, calendar, contacts, and tasks from PCs, the web, and mobile devices. It integrates fully with Active Directory, enabling administrators to use group policies, as well as other administration tools, to manage Exchange Online features across their environment.
Organizations that subscribe to Exchange Online retain control over the messaging services they offer to users, but they do not have the operational burden of on-premises server software. With the Exchange Online hosted plans described in this document, email is hosted on servers that support multiple customers simultaneously. These servers are housed in Microsoft data centers and are accessible to users on a wide range of devices from inside a corporate network or over the Internet.

| Because we're continually improving service features, information in these topics can occasionally be out of sync with your service. If the information here doesn’t match what you’re seeing, you may be using Office 365 pre-upgrade. For pre-upgrade service descriptions, see Office 365 for Enterprise Service Descriptions. To see if you’re using Office 365 after the service upgrade, see Am I using Office 365 after the service upgrade? |
For information about new features in Exchange Online, see What's New in Exchange Online.
Office 365 is available in a variety of plans in order to best meet the needs of your organization. For information about different plans, including standalone plan options and information on moving from one plan to another, see Office 365 Plan Options.
Each user who accesses the Exchange Online service must be assigned to a subscription plan, and each user subscription has its own mailbox. Folders and messages in these mailboxes reside on a computer running Exchange Server at a Microsoft data center.
User subscriptions are not required for conference rooms and shared mailboxes. These special mailbox types do not have login credentials. Instead, licensed users with the appropriate permissions manage them via delegation.
