Microsoft says a new user activity-based expiration policy can be enabled for Office 365 groups by select Azure AD Premium customers starting today. The new policy will allow active groups to avoid being deleted automatically after the group lifetime is reached. Microsoft 365 is part of the Microsoft 365 software bundle which also comes with Windows 10 and EMS (short for Enterprise Mobility + Security), a bundle which in Microsoft’s vision provides customers with the easiest way of enjoying an easy to manage and secure online productivity platform. Users can also restore their groups’ contents after unintentional deletion for several apps including but not limited to SharePoint, Teams, Planner, and Outlook for a period of 30 days.
