Topic Last Modified: 2014-10-02

This section describes available mailbox plans for Exchange Online Dedicated, including mailbox types, the management of mailboxes, and features available to mail clients.

Your organization can purchase Exchange Online Dedicated user subscriptions as a standalone plan or as part of an enterprise suite plan that includes other Office 365 Dedicated services. The following sections describe the key features of each plan type. A Microsoft sales representative can provide additional information regarding Office 365 subscription plans.

As an Exchange Online Dedicated customer, you can provision a messaging plan for each user in your organization. Each mailbox has a messaging plan. Folders and messages in these mailboxes reside within the Exchange Server infrastructure of Exchange Online Dedicated.

To simplify the provisioning process, messaging seat features are packaged according to the standalone Exchange Online Dedicated plan subscription assigned to the user as shown in the following table.

The Configuration Request process can be used to apply the restrictions. Contact your service delivery manager (SDM) for assistance.

2 Volume licensing and streaming delivery options for Office Professional Plus 2013 are described within the Microsoft Office Client Authentication Services section of the Identity and Provisioning service description for Office 365 Dedicated.

In Exchange Online Dedicated, each object held in Active Directory must utilize an Exchange CustomAttribute (also known as Active Directory extension attribute) to hold mailbox size, plan type, feature settings, and other optional provisioning parameters. For more information, see the Office 365 Dedicated and ITAR-support Plans Provisioning Tools Handbook on the Microsoft Managed Solutions Services Provisioning Provider (MMSSPP) & Provisioning Tools Release Documentation & Training Material landing page for existing Office 365 Dedicated customers.

In addition to its primary role to keep the Active Directory of your on-premises environment synchronized with Office 365, the Microsoft Managed Solutions Services Provisioning Provider (MMSSPP) tool is used to assist with the provisioning of additional mailboxes and to set specific service features for each mailbox held in Exchange Online Dedicated. For more information, see Directory Synchronization and Service Provisioning.

Following the provisioning of a mailbox, two self-service mailbox administration options are available within Exchange Online Dedicated for self-service mailbox administration: (a) the menu driven Exchange Admin Center and (b) the command line oriented Windows PowerShell. For a summary of all administration tools, see Administration and Management.
