Microsoft 365 shifts to shared storage pools, cutting capacity for multi-user accounts
Microsoft is consolidating cloud storage for family plans into a single shared pool starting in 2027, a move that dramatically reduces capacity for accounts with multiple heavy users while the tech industry grapples with a storage crunch.
Microsoft has announced a significant restructuring of how it allocates cloud storage across its subscription tiers. Beginning with renewals after May 2, 2027, the Microsoft 365 Family, Premium, and Pro plans will transition from providing 1TB per individual user to a single shared pool of 2TB across all account members. For a household of six subscribers, this represents a 66.6% reduction in total available storage. The company has indicated that some affected users may receive bonus storage when their accounts migrate to the shared model, though it has not disclosed the specific criteria for eligibility.
According to Microsoft, the shift is designed to allocate storage dynamically based on actual household needs rather than fixed per-user quotas. The company contends that the approach reduces the likelihood of individual users exhausting their allocations and allows unused capacity to serve the entire family unit. Any supplemental storage purchased by the primary account holder will extend to all members.
The restructuring creates winners and losers depending on household composition. Families with one dominant user consuming most of the storage while others use minimal capacity stand to benefit. Conversely, a household with four users each consuming 500GB would face mandatory additional purchases, with Microsoft offering 200GB increments starting at $1.99 monthly. An individual subscriber needing more than 1TB might find the Microsoft 365 Family plan at $129.99 annually more economical than the Microsoft 365 Personal plan at $99.99 annually plus $119.88 yearly for extra capacity.
The policy change arrives as the technology industry confronts a significant storage shortage. Hard drive prices surged 46% between September 2025 and January 2026. Enterprise-grade SSDs have experienced even steeper pressure, with 30TB drives commanding $22,600 and remaining unavailable until 2027. While Microsoft has not raised subscription prices, the shift effectively reduces server load while compelling multi-user households with substantial storage demands to pay additional fees.
Alternatives exist but face their own constraints. Google has cut its free cloud storage offering from 15GB to 5GB pending additional security requirements. Backblaze, which markets "unlimited" backups, has revised its terms to allow potential throttling or termination of accounts exceeding "typical usage patterns" or placing "an undue burden." Building a personal network-attached storage system with quality hard drives requires upfront investment and technical knowledge, yet could yield substantial savings over time compared to ongoing subscription costs.
