Microsoft 365 Apps
1. SharePoint Online: Storage quota enforcement updated to align with license limits
How this will affect your organization
We’re updating the way SharePoint Online enforces user storage quotas to ensure they are consistently aligned with license entitlements.
Who is affected
- Microsoft 365 tenants using SharePoint Online
- Users who are currently over the OneDrive for Business storage quota allowed by their assigned license
- Admins who have set user-specific storage limits above licensed entitlements
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, which temporarily restricts write access to existing SharePoint 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 licensed storage limits
- Review OneDrive storage usage across your organization to identify users whose usage exceeds their licensed quota.
- 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.
When will this happen:
late May 2026 and expect to complete in June 2026.
