Users with the DefaultMailboxPlan assigned to their mailbox can create public groups by default. But you can prevent users from creating groups by configuring the role assignment policy assigned to their mailboxes.
Note By default, users with the GalDisabledMailboxPlan assigned to their mailbox can't create distribution groups. For more information, see Mailbox Plans.
To configure the role assignment policy:
Select Manage My Organization > Roles & Auditing > User Roles, and then select the role assignment policy assigned to the users you don't want to create groups.
Under Roles You Can Assign, clear the My Distribution Groups check box, and click Save.
Important Changing a role assignment policy affects all users whose mailbox is associated with the role assignment policy. In this case, none of the users who are assigned the role assignment policy that you configured can create groups.
