Question details

The user needs a way to receive alerts or notifications when a large number of files or folders are deleted from a work OneDrive account to prevent unnoticed data loss.

How to Get Notifications for Mass File Deletions in OneDrive

Product: OneDrive for Business
Device & OS: not provided
Scenario: Managing team files in a shared OneDrive workspace where unexpected mass deletions might occur without warning.
Observed behavior: Folders disappeared from the OneDrive account without triggering a deletion alert, requiring manual recovery from the Recycle Bin.

Before you start

Ensure you have administrative privileges for your organization's Microsoft 365 or OneDrive for Business account, as configuring these notification thresholds requires policy-level access.

Solution 1Recommended

Configure Large-Deletion Confirmation Policies

Use this solution to enforce a policy that prompts users with a warning when they delete a batch of files exceeding a specified threshold.

By default, OneDrive alerts users when more than 200 files are deleted at once in a short period. Administrators can customize this threshold using Microsoft Intune or Group Policy to prevent accidental mass deletions by team members.

Access administration tools

Open Microsoft Intune or your Group Policy Editor with administrative credentials.

Locate the deletion policy

Navigate to the OneDrive policy settings and find the policy named 'Require users to confirm large delete operations'.

Enable the policy

Set the policy to 'Enabled' to activate the mass deletion prompt for your organization.

Set the threshold limit

Configure the 'LocalMassDeleteFileDeleteThreshold' setting to define the exact number of files that will trigger the warning (e.g., lower than 200 if you want stricter alerts).

Deploy changes

Apply and deploy the policy to the affected user groups. It may take some time for the policy to sync across all devices.

Configure Large-Deletion Confirmation Policies

Registry modifications: If modifying these settings via the Windows Registry directly, proceed with caution and ensure you have a backup of the registry before making changes.

Solution 2

Restore Files from the OneDrive Recycle Bin

Use this method to recover folders or files that were already deleted by team members without triggering a notification.
