Question details

A Microsoft 365 administrator needs to know if they can bulk change or remove sensitivity labels from multiple Office documents stored in a specific user's OneDrive.

How to Change Sensitivity Labels in a User's OneDrive

Product: Microsoft 365 / OneDrive
Device & OS: not provided
Scenario: Managing data protection and adjusting security classifications for existing files within a user's cloud storage environment.
Observed behavior: Administrators cannot bulk-change sensitivity labels that users have manually applied, but can adjust automatically applied or lower-priority default labels.

Before you start

Ensure you have the necessary Microsoft Purview Information Protection admin permissions and understand the priority order of your organization's sensitivity labels before modifying policies.

Solution 1Recommended

Adjust Microsoft Purview Policies for Auto-Applied Labels

Modify automatic labeling policies to change or remove lower-priority labels across a user's OneDrive.

Administrators generally cannot bulk-change manually applied sensitivity labels on existing files. However, if the labels were applied automatically or assigned as lower-priority defaults, they can be modified centrally.

Access Microsoft Purview

Navigate to Information Protection

Go to the 'Information protection' section in the left-hand navigation pane and select 'Auto-labeling'.

Edit Label Policies

Review your current default labels, automatic labeling, and mandatory labeling settings. Adjust the policy rules to apply a new label or set the action to 'None' for specific lower-priority classifications.

Apply and Sync

Save the updated policy. The changes will propagate to files across OneDrive where labels were automatically applied.

Adjust Microsoft Purview Policies for Auto-Applied Labels

Manual Labels Limitation: Labels that were manually applied by users have a higher priority and generally cannot be overridden or removed in bulk by admin policies.

Solution 2

Configure Default Sensitivity Labels for Future Files

Set up a default sensitivity label at the SharePoint or OneDrive document library level to ensure future files are classified correctly.

Frequently Asked Questions

Can an administrator bulk remove manually applied sensitivity labels in OneDrive?

No, in the current sensitivity-label environment, administrators cannot bulk-change or remove labels that users have manually applied to existing files. Manual labels take precedence over automated Microsoft Purview policies.

How can I change an Office sensitivity label to 'None'?

Labels can be set to 'None' in Office applications only if the previous label was automatically applied with a lower priority or assigned as a lower-priority default label.

How do default sensitivity labels work in document libraries?

When configured, a default sensitivity label is automatically applied to all new files created in or uploaded to that specific SharePoint or OneDrive document library, streamlining initial document security without retroactively altering old manual labels.
