Exchange Online Service Description

 

Applies to: Office 365

Topic Last Modified: 2016-11-18

Are you looking for a feature comparison of Office 365 subscriptions that include Exchange Online? If so, the Exchange Online service description article is what you need. You’ll also learn about system requirements as well as storage and recipient requirements.

Microsoft Exchange Online is a hosted messaging solution that delivers the capabilities of Microsoft Exchange Server as a cloud-based service. It gives users 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.

To compare features across plans, see Compare Office 365 for Business plans.

TipTip:
You can export, save, and print pages in the Office 365 Service Descriptions. Learn how to export multiple pages.

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 and access them via delegation.

For system requirements for Office 365, the monthly subscription-based service available for business, education, and government organizations, please see Office 365 system requirements.

For information about the storage and recipient limits available in the Exchange Online subscription plans, see Exchange Online Limits.

If your organization currently has subscriptions to Office 365 Small Business, Office 365 Small Business Premium, or Office 365 Midsize Business, visit your Message Center in the Office 365 admin center or talk to your Office 365 provider for more details on how the new Office 365 Business plans impact you. To learn more about the new Office 365 Business plan family, see New Office 365 plans for small and mid-sized businesses.

NoteNote:
1   Requires an Exchange Online Archiving (EOA) subscription for each on-premises mailbox user that has a cloud-based archive.
2   Azure Rights Management (RMS) isn’t included but can be purchased as a separate add-on (or added for free to the Office 365 Education plan) in order to enable the supported IRM features. Office 365 Message Encryption depends on Azure RMS.
3   Windows Server AD RMS is an on-premises server that must be purchased and managed separately in order to enable the supported IRM features.
4   Transport rules are made up of flexible criteria, which allow you to define conditions and exceptions, and actions to take based on the criteria. The available criteria and actions differ between Exchange Online, and Microsoft Exchange Server 2013. For a list of available criteria and actions, see the corresponding criteria and actions topics for each product.
5   For Exchange 2013, DLP requires an Exchange Enterprise Client Access License (CAL). For more information about CALs and server licensing, see Exchange Server Licensing.
6   Exchange Server 2013 has most of the same built-in anti-spam capabilities as Exchange Server 2010. For information about the benefits of Exchange hosted spam filtering over the on-premises offerings, see Benefits of Anti-Spam Features in Exchange Online Protection Over Exchange Server 2013.
7   Only accessible via direct access to the Exchange admin center (EAC) management interface.
8   Exchange Server 2013 uses only the Microsoft anti-malware engine. Exchange Online uses multiple anti-malware engines to scan inbound, outbound, and internal messages for malware.
