Effective February 18, 2021, extended offline access and device-based subscriptions are available for Microsoft 365 Apps for enterprise (previously called Office 365 ProPlus). Those features remove critical blockers and enable customers to deploy Microsoft 365 across their entire environment, streamlining deployment and administration.
Workers in secure or remote environments who are offline for long periods of time can continue using Microsoft 365 Apps to stay productive on-the-job, now being provided with extended offline access to enable devices to stay activated without connecting to the internet for up to 180 days.
In device-based subscriptions for Microsoft 365 Apps the license is assigned to the device, hence workers aren’t required to have their own Azure Active Directory identity. To deploy a device-based subscription, you simply purchase the required number of Microsoft 365 licenses and assign a license to a device group in the Microsoft 365 admin center.
