Product
Microsoft OneDrive
Device & OS
not provided
Scenario
Attempting to free up space by deleting files after an organization or school unexpectedly reduces the total allowed OneDrive storage capacity.

Before you start

Verify your current OneDrive storage usage and quota limits by logging into your Microsoft 365 account on the web before attempting to request changes.

Solution 1Recommended

Request a Temporary Storage Increase from Your Administrator

To unlock your account and allow file deletions, your school or tenant administrator must temporarily increase your storage quota.

When an account is significantly over its quota, Microsoft 365 restricts file operations, including deletions. This frequently occurs for Education accounts transitioning from 1 TB to 100 GB limits.

1
Contact Support

Identify your Microsoft 365 tenant or school IT administrator and reach out to their support desk.

2
Request Quota Adjustment

Ask for a temporary OneDrive storage quota increase so your account can be un-frozen, allowing you to access and delete files.

3
Wait for Implementation

Wait for the administrator to apply the temporary storage increase to your account via the SharePoint admin center.

4
Delete Unnecessary Files

Once the temporary quota is active, log in to OneDrive on the web and immediately move or delete large files to get below your permanent limit.

Request a Temporary Storage Increase from Your Administrator
For Administrators: Administrators can review and adjust user storage limits by visiting the SharePoint admin center and modifying user profiles as per Microsoft's documentation.

Frequently Asked Questions

Why did my OneDrive storage quota suddenly drop to 100 GB?

Microsoft 365 Education accounts recently underwent policy changes regarding their default storage limits. This often resulted in previously allocated 1 TB quotas being reduced to 100 GB per user by the institution.

Will I lose my files if my OneDrive remains over the storage limit?

Yes, if your account remains significantly over the storage quota for an extended period, Microsoft policies dictate that data may eventually be deleted automatically. It is crucial to back up your important files promptly.

Why doesn't deleting files free up space immediately in OneDrive?

Files you delete are simply moved to the Recycle Bin and continue to count against your storage quota. You must empty both the primary and second-stage recycle bins to permanently erase the files and free up the space.
