Microsoft has published a support page detailing changes to OneDrive storage allotments for Microsoft 365 subscribers on Family, Premium, and Pro plans. Under the current system, each of up to six users receives 1TB of storage, totalling 6TB. The new policy replaces per-user caps with a shared pool: Family and Premium subscribers get 2TB to divide among six users, while Pro subscribers receive 5TB. This means a fully utilised Family or Premium account loses up to 4TB of combined capacity; a fully utilised Pro account loses up to 1TB.
Microsoft frames the change as a flexibility improvement. "The goal is to provide a more flexible experience," the company states. "Shared storage helps ensure that one person doesn't run out of space while other members have unused storage available." Under the new system, an individual user can exceed the previous 1TB cap as long as the shared pool has room. However, if multiple people on a plan each use a significant portion of the pool, heavy uploads may become constrained. Microsoft notes that users can purchase additional storage.
Anticipating backlash, the support page includes instructions for cancelling subscriptions. The company says some existing customers may qualify for temporary bonus storage. New Family, Premium, and Pro subscribers saw the new storage schema take effect on Thursday. Current subscribers will face the change when their plans renew on or after May 2, 2027, and Microsoft says it will send reminders ahead of that date.
Reaction has been sharply negative. A thread on Reddit's Microsoft 365 subreddit is filled with complaints, with users suggesting they will cancel rather than accept the reduction. One popular post reminds subscribers to turn off auto-renewal. The Register notes that Microsoft has a history of reducing cloud storage allotments: Office 365 once offered unlimited storage until some users took the offer literally, and education storage was drastically cut in 2024, prompting McGill University to reduce students' allowances to 20GB. The article cautions that the new 2TB shared pool may itself be altered in future.
