Question details
The user's OneDrive for School account has reached its storage limit, and standard attempts to delete files to free up space are failing.

- Product
- OneDrive for School
- Device & OS
- not provided
- Scenario
- Trying to free up storage space on an over-limit educational OneDrive account but encountering errors when deleting files.
- Observed behavior
- Files cannot be removed from the full account, which may be due to unemptied recycle bins, institutional retention policies, a Preservation Hold Library, or restrictive education storage limits.
Ensure you are logged into your school account via the OneDrive web portal on a computer, as advanced storage metrics and second-stage recycle bins are easiest to access from a web browser.
Empty the First and Second-Stage Recycle Bins
Files you delete are moved to the recycle bin and still count against your storage quota until permanently erased from both recycle bin stages.
OneDrive features a two-stage recycle bin system to prevent accidental data loss. To fully free up storage space, you must clear both stages.
Open OneDrive on the web and click on 'Recycle bin' located in the left-hand navigation menu.
Click the 'Empty recycle bin' button at the top of the page and confirm the deletion.
Scroll to the very bottom of the Recycle Bin page and click on the 'Second-stage recycle bin' link.
Click 'Empty recycle bin' again in this secondary view to permanently delete the files and free up your storage.

Check Storage Metrics for a Preservation Hold Library
Determine if your school's retention policies are secretly hoarding deleted files in a hidden Preservation Hold Library.
Contact the School's Microsoft 365 Administrator
If retention policies are active or your account is locked in read-only mode, only your school's IT admin can resolve the issue.
Need to Finish Your Assignments While OneDrive is Full?
If your school's OneDrive is locked and you cannot save or edit your Microsoft Office documents, switch to WPS Office. It is a free, lightweight suite that lets you save files locally and provides full compatibility with all your coursework formats.
- 1. Download WPS Office: Visit the official WPS website and download the free version for your PC or Mac.
- 2. Open Your Coursework: Launch WPS Office and easily open your existing .docx, .xlsx, or .pptx files.
- 3. Save Locally: Edit your assignments and save them directly to your computer's hard drive to bypass OneDrive limits.

Frequently Asked Questions
What is a Preservation Hold Library in OneDrive?
A Preservation Hold Library is a hidden folder in Microsoft 365 where files are retained to comply with legal or institutional retention policies. If your school has enabled this, deleted files are moved here instead of being permanently erased, which still counts against your storage quota.
Why did my OneDrive for School suddenly become read-only?
If your account exceeds the storage limit set by your educational institution (often 100 GB for Microsoft 365 Education plans), Microsoft automatically places the account in a read-only state. You will not be able to upload, edit, or delete files until the administrator lifts the restriction.
Can I personally disable the retention policy on my school OneDrive?
No. Retention policies are managed globally by your institution's Microsoft 365 administrator. Students and staff cannot disable or bypass these policies. You must contact your IT department to request changes.
How long does it take for OneDrive to show free space after deleting files?
After you permanently delete files by emptying both the first-stage and second-stage recycle bins, it can take up to 24 hours for the Microsoft servers to recalculate and display your newly available storage space.
