Contact Your IT Administrator to Verify Microsoft 365 Licensing
Storage limits for school and enterprise accounts are managed at the organizational level, meaning your IT administrator must check for licensing or tenant-wide policy changes.
Microsoft frequently updates its educational and enterprise storage plans. In many cases, schools lose eligibility for certain legacy free tiers, or administrators implement tenant-wide policies that restrict individual user storage from 1 TB down to 100 GB to better manage a pooled storage quota.
Find the contact information for your organization's IT helpdesk, school technology department, or the dedicated Microsoft 365 administrator.
Ask the administrator to check your account's current Microsoft 365 license status via the Microsoft 365 Admin Center to see if your subscription tier was recently downgraded.
Request that the administrator review the specific OneDrive storage allocation applied to your user profile and confirm if new tenant-wide storage limits have been enforced.

Frequently Asked Questions
Will I lose my files if my OneDrive storage is reduced to 100GB?
If your currently stored files exceed the new 100GB limit, your OneDrive will go into a read-only state. You will not lose your files immediately, but you will be blocked from uploading new files, editing existing ones, or syncing data until you delete enough files to get below the 100GB threshold.
Can I personally upgrade my school OneDrive storage back to 1TB?
No. School and enterprise OneDrive storage limits are managed entirely by your organization's IT administrator based on institutional licensing. You cannot purchase additional personal storage for a managed educational or enterprise account.
How can I quickly free up space on my OneDrive?
You can free up space by navigating to your OneDrive on the web, sorting your files by size to identify large documents or media, deleting unnecessary files, and permanently emptying the OneDrive recycle bin. Alternatively, download older files to a local hard drive before deleting them from the cloud.
Why did my school change the storage limit without asking?
Schools must comply with Microsoft's changing license terms. Recently, Microsoft shifted from offering individual unlimited or 1TB educational quotas to providing a pooled storage limit for the entire institution. To ensure all students and staff have fair access, IT administrators must enforce lower individual caps, typically 100GB.
