Updated June 1,3, 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 updatingfixing issues in the way SharePoint Online enforcesOneDrive for Business applies user storage quotas to ensure they are consistently aligned with license entitlements.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 inearly July 2026 (previously late May 2026May) and expect to complete in Junemid-July 2026 (previously June).
How this affects your organization
Who is affected
- Microsoft 365 tenants using
SharePoint OnlineOneDrive for Business - Users who are currently over the OneDrive for Business storage quota allowed by their assigned license or extended storage
- Admins who have set user-specific storage limits above licensed entitlements or extended storage
What will happen
- User storage quotas will be re-evaluated against license limits during the refresh process.
- Users whose OneDrive for Business storage usage exceeds their licensed quota will be placed into a read-only state
,per existing policy, which temporarily restricts write access to existing SharePointOneDrive content until storage usage is remediated. - This includes scenarios where:
- An admin-set user quota exceeds the license allowance, or
- A user with an EDU license exceeds their licensed storage limit.
- No changes are made for users who are within their licensed storage limits.
What you can do to prepare
- Identify users exceeding OneDrive for Business licensed storage limits
- Take corrective action for affected users. For users exceeding their licensed storage limits:
- Upgrade the user’s license to increase available storage, or
- Work with the user to reduce storage usage to within licensed limits.
- Inform your helpdesk and SharePoint admins about this change so they can support users who may be placed into a read-only state.
- If all users are within their licensed storage quotas, no action is required.
