Microsoft is currently implementing significant adjustments to the cloud storage structure for both its Microsoft 365 Family and Premium subscription tiers. Previously, each individual member enjoyed a generous, independent 1TB of storage space. However, Microsoft has astonishingly decided to change Microsoft 365 storage. This forces all members to share a significantly reduced maximum pool of merely 2TB.
This drastic adjustment represents exceptionally terrible news for high-frequency OneDrive users. Many individuals who utilize family plans are professional power users for whom even 1TB was barely sufficient. Consequently, shrinking the total quota stretches their available storage painfully thin. Continuing to rely on a shared Family plan will likely fail to satisfy their demanding daily usage requirements.
The Details of the Adjusted Policy
Historically, a Family subscription accommodated up to six members, including the primary account holder. Each member received an isolated 1TB of OneDrive storage. This resulted in a robust 6TB of total available space per subscription. Following this controversial adjustment, the total spatial capacity of the Family subscription plummets drastically from 6TB down to a shared 2TB pool. Consequently, all six members must now share this 2TB. This leaves an average of merely 333GB of storage space per individual.
Microsoft attempts to justify this by stating that shared capacity allows members to utilize space left idle by others. This is provided, of course, that idle space actually exists. Importantly, files remain the exclusive property of their respective accounts, and members inherently cannot view documents stored by others. If the shared storage limit is exceeded, users face the grim task of either purging files or purchasing additional storage quotas.
Crucially, this adjustment does not impact the Microsoft 365 Personal subscription. Personal subscribers retain their independent 1TB of storage space. However, the cost of a Personal subscription significantly exceeds the per-person price of a shared Family plan. Consequently, users must carefully evaluate their specific usage patterns to decide whether to remain in a constrained shared plan. Or they may transition to a costlier Personal subscription.
The Option to Expand to 10TB
Furthermore, Microsoft noted that if family members collectively store files exceeding the new 2TB limit, they must either delete content or purchase an expanded quota. Microsoft permits extending the subscription storage up to a massive 10TB. Moreover, certain eligible existing subscribers might receive complimentary transitional extra space.
Currently, however, Microsoft has not clarified whether all existing subscribers will automatically receive this transitional space. Nor have they published the precise pricing structure for the various expanded subscription tiers. Therefore, users struggling with insufficient space must vigilantly monitor future announcements from Microsoft. They should also prepare to pay a premium to acquire the necessary storage capacity.
Implementation Timeline for Renewals and New Subscriptions
Microsoft’s detailed transition notes explain that all newly activated or upgraded subscriptions will be subject to the shared storage mechanism beginning October 8, 2026. Conversely, users who previously established Family or Premium subscriptions will transition to the new shared model. This will occur upon their first renewal occurring on or after May 2, 2027.
If existing subscribers prematurely upgrade their packages before that date, the new policy takes effect immediately. (This implies that simply renewing, rather than upgrading, might temporarily preserve the independent space, though this remains uncertain and warrants cautious operation). Finally, it is crucial to understand that exceeding the family shared storage quota does not trigger immediate file deletion. Microsoft graciously provides users with a one-year grace period to manage oversized files. However, if these files remain unaddressed beyond that year, Microsoft reserves the right to delete them permanently.
