Summary:
OneDrive for Business will fix storage quota bugs to align user quotas with license limits, rolling out early July to mid-July 2026. Users exceeding licensed storage may be set to read-only until usage is reduced or licenses upgraded. Admins should identify and address over-quota users accordingly.
Details:
Updated June 3, 2026: We have updated the content and timeline. We are not proceeding with gov clouds at this time. We apologize for any inconvenience.
[Introduction]
We're fixing issues in the way OneDrive for Business applies user storage quotas to ensure they are consistently aligned with license entitlements and current product behavior. This change fixes an issue where user-specific storage limits could be incorrectly applied during quota refreshes, which could result in inaccurate storage enforcement. These updates help ensure predictable storage behavior and improve reliability for admins managing storage at scale. These fixes will be beneficial to admins, but there is a small percentage of users who will have their OneDrive for Business storage quota adjusted to match their license entitlement.
[When this will happen]
General Availability (Worldwide): We will begin rolling out early July 2026 (previously late May) and expect to complete in mid-July 2026 (previously June).
