Topic Last Modified: 2014-09-29

Microsoft Exchange Online is an enterprise-class, remotely hosted, email messaging solution that uses the power of Microsoft Exchange Server to provide the mission-critical messaging services that businesses require today. Messaging content held in Exchange Online is accessible to users on a wide range of devices from inside your corporate network or over the Internet. The service gives users single sign-on access to email, calendar, and contacts from virtually anywhere and at any time.

Microsoft offers several versions of Exchange Online for enterprise environments. In comparison to the commonly known “Exchange Online” service provided by a virtualized environment on multi-tenant hardware, the Exchange Online Dedicated offering is a premium service provided to a single tenant on dedicated hardware. When your organization subscribes to a dedicated plan of Exchange Online for enterprises, your messaging content is hosted on dedicated servers that are housed in reliable, security-enhanced, Microsoft data centers.

Microsoft operates data centers around the world to support online services. For Exchange Online Dedicated, data centers equipped with highly reliable information systems and networking equipment are used to provide messaging solutions and to deliver 99.9 percent uptime. The service is backed by service level agreements (SLAs) that guarantee optimal performance.

Organizations that choose Exchange Online Dedicated have exclusive use of the servers that are needed to support their specific messaging requirements. Automated synchronization to allow your on-premises directory information to be synched continuously with your directory in the Microsoft data centers also is provided. The copy of your on-premises directory held within Office 365 Dedicated allows users to have seamless access to messaging applications from a wide range of devices while within the corporate network or on the Internet. Your organization also retains control over the messaging services offered to your users. The IT personnel of your organization can use the features of Active Directory to control service availability through existing group policies.

The Exchange Online service is built on the latest Exchange Server 2013 release and is integrated with other messaging components to provide a comprehensive, remotely hosted messaging service for the enterprise. The diagram below is a representation of the high-level infrastructure of the Exchange Online Dedicated environment.

The Exchange Online service offers the following benefits:

  • Flexible messaging services. Email, shared calendar, Outlook connectivity, and Microsoft Outlook Web App provide the flexibility to meet diverse and evolving organizational needs.

  • Regulatory compliance features. Meeting the increasingly complex regulatory requirements is eased with Sarbanes-Oxley and SAS 70 Type II self-assessment and audit support.

  • Multi-level data protection. Safeguards are applied on multiple fronts, from message encryption support to the multilevel message filtering capabilities that include spam and virus protection, to the logical and physical security that protects your information in the data centers.

  • Mobility device support. Mobility features provide the messaging agility that organizations require to stay competitive in the marketplace, allowing users to easily access their hosted services and stay connected anywhere in the world. At the same time, remote device wipe and policy provisioning help to ensure that sensitive data is protected.

  • Remote administration of key features. Organization and user administration features are designed to help reduce Service Desk escalations, enhance service management, and empower users.

  • The content of this service description applies to the high availability platform of the Exchange Server 2013 operating environment, available to existing Exchange Online Dedicated customers.

All existing customers will gradually be migrated to the new release. Contact your Microsoft account team for additional information.
