Microsoft 365 Family and Premium subscriptions include AI features and AI credits, but those AI benefits are restricted to the subscription owner only and cannot be shared with other family members.
For Microsoft 365 Family/Premium:
- AI features like Copilot in Word, Excel, PowerPoint, Outlook, and Designer are available only to the subscription owner.
- AI credits (for Copilot in Microsoft 365 apps, Designer, etc.) are also only available to the subscription owner.
- Family members can use the Microsoft 365 apps themselves, but not the AI features, even if they are part of the same Family subscription.
This is by design and there is currently no way to designate specific shared accounts (such as a spouse) to use the subscription owner’s AI credits. If another family member wants access to AI features and their own AI credits, they must have their own qualifying subscription (for example, Microsoft 365 Personal or Microsoft 365 Premium) associated with their own Microsoft account.
Note that when multiple Microsoft accounts are signed into the same app, AI benefits still belong only to the account that owns the eligible subscription; AI credits are counted against that owner’s subscription when Copilot is used, and they are not shared as a pool across family members.
