Microsoft 365 Family and Premium to Share Copilot AI With All Six Users
Microsoft will let Microsoft 365 Family and Premium subscribers share Copilot and AI features with up to five other people on the plan. Until now, those benefits were restricted to the primary account holder. The Verge
The same sharing applies to the core parts of the subscription. Family and Premium members will be able to share Office apps and OneDrive storage access with up to five others, keeping the familiar six-person structure.
The storage change is structural. Microsoft is shifting Family and Premium OneDrive storage from 1TB per account to 2TB of shared storage for the whole plan. Existing subscribers in eligible markets may qualify for temporary bonus storage to ease the move from individual quotas to a pooled limit.
Microsoft 365 Premium, which bundles Copilot Pro with Microsoft 365 Family benefits, costs $19.99 per month. It is aimed at households that want full Family sharing and higher AI limits. Microsoft documentation describes it as offering extensive usage limits for AI features and exclusive access to Copilot features, with AI credits that work in Word, Excel, and PowerPoint. The Verge
Under the system being replaced, Personal and Family subscribers received a monthly allowance of AI credits for Copilot in Word, Excel, PowerPoint, and Outlook. That system dates to January 2025, when Copilot was added to Microsoft 365 Personal and Family. Family is listed as including Copilot AI in those four apps for up to six users, and Copilot is documented across Personal, Family, Premium, and Pro subscriptions.
Support pages still show the old rule. They state that on a shared Family or Premium subscription, AI benefits such as Copilot in the desktop apps are limited to the owner. Separate guidance says AI features in Premium cannot be shared, extended storage options cannot be shared, and minimum age limits may apply to AI features in Premium.
The update follows the new Copilot with Home, Code and Autopilot, detailed on Sept. 25. That release expands Copilot from an assistant inside apps to a wider surface covering personal context, development work, and automated tasks.
The broader context here is how these plans are actually used in households. When only one person could use Copilot in the desktop apps, shared documents ended up in different states and the monthly credit allowance was hard to track. Letting all six seats use Copilot fits how Word, Excel, and Outlook files pass between people.
In my view, the storage side needs close attention. Individual quotas kept heavy users separate. A single 2TB pool is simpler to manage but creates contention, since one person storing large photo libraries or PST archives can limit space for the other five. How Microsoft sizes the transitional bonus storage, and how long it lasts, will decide whether households feel this as simplification or as a cut. Over time, shared AI access matters more. Quotas can be adjusted, but giving everyone the ability to prompt, summarize, and generate inside everyday work tools changes daily habits in a way that lasts.
