Mailbox Plans

Applies to: Office 365 for enterprises, Live@edu

A mailbox plan is a template that automatically populates multiple mailbox properties and assigns default permissions to users. You use mailbox plans to provision mailboxes for a particular user population with a common default configuration. For example, in Microsoft Live@edu, you can assign a mailbox plan to students, which hides their contact information from the shared address book. This mailbox plan can help satisfy some of the privacy and compliance requirements of acts such as the Family Educational Rights and Privacy Act (FERPA) in the United States or the Data Protection Act in Europe. You can assign a different mailbox plan to faculty members so that their contact information is displayed in the shared address book.

All mailbox creation is based on a mailbox plan. Creating mailboxes from a template means that users are created with consistent settings and with the appropriate set of permissions.

What mailbox plans are available?

The availability of mailbox plans is determined by the selections that you make when you enroll your domain. That means not all organizations will have more than one mailbox plan. The mailbox plan that is set as the default is always assigned to new users you create.

  • Microsoft Office 365 for enterprises   There are three mailbox plans: ExchangeOnline, ExchangeOnlineDeskless, and ExchangeOnlineEnterprise. These mailbox plans correspond to the subscriptions and licenses that administrators purchase and assign in the Microsoft Office 365 portal as follows.

    Exchange Online (Plan 2)

    ExchangeOnlineEnterprise

  • **Microsoft Live@edu**   There are two mailbox plans: DefaultMailboxPlan and GalDisabledMailboxPlan. If you don’t want student information to be discoverable by other students, assign the GalDisabledMailboxPlan to the mailbox.

Important   Mailbox plans correspond to Office 365 license types. When you create a new cloud-based mailbox using the Exchange Control Panel, all mailbox plans are available, even if the corresponding licenses aren't included in your organization’s subscription to Microsoft Office 365.

Why does this matter? If you create a mailbox and assign a mailbox plan that corresponds to a license that gives users more features than you paid for, they may not be able to access their mailbox or they may lose data after you license the mailbox in the Office 365 portal. Be sure to assign a mailbox plan that supports your organization’s licenses.

Modify a mailbox plan

You can modify a mailbox plan by changing the roles associated with it. For more information, see Role Assignment Policies in Exchange Online.

View the settings in a mailbox plan

You can use Windows PowerShell to view the settings in a mailbox plan.

To learn how to install and configure Windows PowerShell and connect to the service, see Use Windows PowerShell in Exchange Online.

To view the settings of all the mailbox plans without truncating the results, run the following command:

Get-MailboxPlan | ConvertTo-Csv > "<file name>.csv"

Open the resulting file in an application like Microsoft Office Excel. Many of the columns, such as GUID, aren't very interesting. Some columns may contain a blank value, which means the setting isn't controlled by the mailbox plan. Some settings can be changed per user. For example, if the mailbox plan enables POP3 access to mailboxes by default, you can customize a user to disable POP3 access to their mailbox.

The following table describes some of the interesting settings that are controlled by mailbox plans, and indicates whether the values can be changed per user.

Next steps

  • You can make the mailbox plan that you assign most frequently the default mailbox plan. To learn how, see View and Set a Default Mailbox Plan.
  • To specify a mailbox plan when you provision users, or assign a different mailbox plan to an existing user, see Assign a Mailbox Plan.
    Note   You can change the mailbox plan of an existing user using the Exchange Control Panel or Windows PowerShell in Live@edu only. In Office 365 for enterprises, the only way to change the mailbox plan of an existing mailbox is to assign a different subscription or license in the Microsoft Office 365 portal.
  • If a Live@edu administrator wants to assign a mailbox plan to many existing users at the same time, see Assign a Mailbox Plan to Many Users' Accounts with Windows PowerShell in Live@edu.
    Note   This procedure is valid in Live@edu only.
