Microsoft will expand access to its AI-powered Office features, including Copilot, for Microsoft 365 Family and Premium subscribers. Users on these plans can now share AI usage with as many as five additional people, alongside existing access to Office applications and OneDrive storage.
The tradeoff is structural: instead of each account holder receiving 1TB of individual storage, plans now limit the household to a shared 2TB pool across all members.
Microsoft frames this as increasing storage flexibility for families where one member might exceed 1TB. The adjustment, however, effectively positions the company to upsell additional OneDrive storage to households that consume more than 2TB—a threshold many productivity-heavy families cross.
Existing subscribers in eligible markets may qualify for transitional bonus storage, according to a Microsoft support note. The company also stated plans to provide support for families with high storage demands.
The changes arrive a year after the launch of Microsoft 365 Premium, priced at $19.99 a month, which bundles Copilot Pro with a Microsoft 365 Family subscription.
The shift to "more flexible AI usage" could also mean some subscribers face increased costs depending on their Copilot consumption patterns. This suggests Microsoft is laying groundwork for variable pricing or tiered usage models for heavy AI users.
The strategy reflects Microsoft's effort to extract margins from its massive Office installed base. By bundling AI access across household members while constricting the storage baseline, the company aims to drive higher-value tier adoption and per-user pricing in its consumer subscription business—a critical offset as cloud infrastructure spending for AI model training continues to balloon.
