A mailbox plan is a template that automatically populates multiple user properties and assigns default permissions to new or existing user accounts. You use mailbox plans to provision accounts for a particular user population with a common default configuration. For example, you can assign a mailbox plan to student users that 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 user account creation is based on a mailbox plan. Creating user accounts from a template means that users are created with consistent settings and with the appropriate set of permissions.
Mailbox plan availability is determined by the selections that you make when you enroll your domain in Outlook Live. 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.
Outlook Live includes two mailbox plans for Microsoft Live@edu: >DefaultMailboxPlan and >GalDisabledMailboxPlan. If student information shouldn't be discoverable by other students, assign the GalDisabledMailboxPlan to the user account.
You can modify a mailbox plan by changing the roles associated with it. For more information, see Role Assignment Policies.
The following table describes the interesting settings that are controlled by mailbox plans and the default values for each mailbox plan. Where indicated, you can change a value per user. For example, if the mailbox plan enables POP3 access by default, you can customize a user’s properties to disable POP3 access.
