Microsoft is replacing the per-person OneDrive allowances in Microsoft 365 Family and Premium with one pool shared by everyone on the subscription. Under the previous arrangement, the primary subscriber and as many as five additional members could each receive 1TB, creating a theoretical 6TB total. The new model gives those same six people a combined 2TB.
The quota is shared, but the files are not. Microsoft’s support document says each member can access only their own files unless they explicitly share them. It also says purchased storage add-ons and eligible members’ free storage grants contribute to the common pool.
When the new limit applies
New and upgraded subscriptions have used shared storage since October 8, 2026. Existing Family and Premium subscribers generally move to it after their first renewal on or after May 2, 2027. An upgrade before that date, such as moving from Family to Premium, can trigger the shared model early. A downgrade alone does not.
Some existing customers in eligible markets might receive transitional bonus storage when the new model reaches their account. Microsoft has not specified a universal bonus amount, and it says customers will receive details before the change applies.
For households already using more than 2TB, the transition does not mean immediate loss of access. Microsoft says customers who exceed the limit can continue accessing their files for up to one year while they reduce usage, buy additional storage, or change plans. Add-ons can raise the subscription’s total storage to as much as 10TB.
Microsoft presents the single pool as more flexible because one member can use space that others leave unused. The trade-off is a much lower maximum included allowance for families that previously spread data across several 1TB accounts.
