Microsoft 365 Family and Premium plans will switch to shared storage and AI credit pools

Microsoft will replace per-user OneDrive allowances on Microsoft 365 Family and Premium plans with a shared 2 TB storage pool, down from 6 TB across six accounts.

Heavy users could face bills that double or triple, since each extra 1 TB adds $10 a month, while family members will be able to share a single AI usage allowance. New and upgraded subscriptions get shared storage starting Oct.

8, 2026, and existing subscribers move at their first renewal on or after May 2, 2027.
