The user needs to delete documents from the SharePoint Preservation Hold Library but is blocked by Microsoft 365 retention controls.

How to Delete Files from the SharePoint Preservation Hold Library

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Attempting to clean up storage or remove specific files from a SharePoint site's Preservation Hold Library.
Observed behavior: Files cannot be permanently deleted because they are locked by retention labels, DLP policies, or active eDiscovery holds.

Before you start

Ensure you have global administrator or compliance administrator permissions in Microsoft 365 to access the Microsoft Purview compliance portal.

Solution 1Recommended

Review and Remove Policies in Microsoft Purview

Files remain in the Preservation Hold Library as long as retention or eDiscovery holds apply. Removing or excluding the site from these policies is the primary way to allow deletion.

Microsoft 365 prevents data deletion from sites under active compliance policies. You must identify which policy is locking the site and remove it.

Access Microsoft Purview

Navigate to the Microsoft Purview compliance portal and log in with your administrative credentials.

Check Retention Policies

Go to 'Data lifecycle management' and 'Records management' to look for active retention policies or labels currently applied to the affected SharePoint site.

Check eDiscovery Holds

Navigate to 'eDiscovery' to ensure the SharePoint site is not part of an active eDiscovery case hold.

Modify or Remove the Hold

Exclude the specific SharePoint site from the active policy, or delete the policy entirely if it is no longer required by your organization.

Wait for Processing

Wait for the policy removal to propagate across the tenant. This may trigger a 30-day delay hold, after which the files can be permanently deleted.

Grace Period: Even after removing a policy, Microsoft 365 applies a 30-day delay hold to prevent accidental data loss. You must wait for this period to expire before deletion is permitted.

Solution 2

Run Microsoft 365 Support Diagnostics

Use the built-in Microsoft 365 admin diagnostic tools to identify and resolve stuck retention or grace eDiscovery holds.

Solution 3

Escalate to Microsoft Support

If policies are removed, the grace period has passed, and diagnostics fail, manual backend intervention by Microsoft is required.

Frequently Asked Questions

Why are my files automatically moved to the Preservation Hold Library?

When a SharePoint site is governed by a retention policy, DLP policy, or eDiscovery hold, any files that are modified or deleted by users are automatically copied to the Preservation Hold Library. This ensures compliance and prevents permanent data loss during litigation or audits.

How long does it take for files to be deleted after removing a retention policy?

Once a retention policy or eDiscovery hold is successfully removed from a SharePoint site, Microsoft 365 typically applies a 30-day delay hold (grace period) to prevent accidental deletion. The files can only be permanently deleted after this 30-day period expires.

Can a site owner directly delete the Preservation Hold Library?

No, the Preservation Hold Library is a system-managed compliance library. It cannot be manually deleted or bypassed by site owners or even administrators as long as compliance policies or holds are actively applied to the SharePoint site.

Does emptying the SharePoint recycle bin remove files from the Preservation Hold Library?

No. Emptying the standard SharePoint recycle bin simply triggers the system to move the deleted items into the Preservation Hold Library if a retention policy is active. They will remain securely stored there until the policy expires.
