Question details

The user needs to free up storage space that has been entirely consumed by files locked inside the OneDrive Preservation Hold Library.

How to Free Space Used by the OneDrive Preservation Hold Library

Product: Microsoft OneDrive
Device & OS: not provided
Scenario: A user's OneDrive storage limit has been reached because organizational retention policies are saving large amounts of data in the background.
Observed behavior: Files in the Preservation Hold Library cannot be deleted or emptied manually by the end user, causing the OneDrive account to run out of usable storage.

Before you start

Check your current OneDrive storage metrics to confirm that the storage is indeed being consumed by the Preservation Hold Library rather than standard user files.

Solution 1Recommended

Contact Your IT Administrator to Manage Retention Policies

Since the Preservation Hold Library is enforced at the organization level, end users cannot empty it. You must request assistance from your Microsoft 365 administrator.

The Preservation Hold Library is a compliance feature designed to prevent data loss. It automatically stores copies of modified or deleted files based on an organization's retention policy. End users do not have the necessary permissions to override or bypass these policies.

Identify your IT support contact

Locate the help desk email, ticketing system, or IT department phone number for your university or organization.

Request a policy review

Explain that your OneDrive storage is full due to the Preservation Hold Library. Ask the administrator to review the retention policy applied to your account to see if the hold can be adjusted or removed.

Ask for a storage allocation increase

If the compliance policies mandate that the hold cannot be removed, ask your IT department to increase your total OneDrive storage quota so you can continue working.

Contact Your IT Administrator to Manage Retention Policies

Do Not Attempt Manual Deletion: Do not attempt to delete the Preservation Hold Library or its contents directly. The system will block the action. Once the administrator resolves the policy or storage limit, ordinary files will become manageable again.

Solution 2

Free Up Standard Storage Space (For Mobile and iPad Users)

If you are struggling with low space and just need simple instructions to delete ordinary, non-preserved files from your iPad or mobile device.

Frequently Asked Questions

What is the OneDrive Preservation Hold Library?

It is a hidden library in OneDrive that automatically stores copies of your modified or deleted files to comply with an organization's legal, regulatory, or administrative retention policies.

Can I manually delete files from the Preservation Hold Library?

No. End users do not have the required permissions to delete or modify files stored in this library. It is strictly controlled by your organization's Microsoft 365 administrators.

Will the files in the hold library stay there forever?

Not necessarily. Files are kept only for the duration specified by your organization's retention policy. Once that specific retention period expires, the files are typically removed automatically.

Does the Preservation Hold Library count against my total OneDrive storage limit?

Yes, all files captured by the Preservation Hold Library consume your allocated OneDrive storage quota. If a massive amount of data is held, it can easily lead to a full storage warning.
