Microsoft Information Protection (MIP)
Device & OS
not provided
Scenario
An organization wants to lock sensitivity labels on sensitive documents, preventing end-users from intentionally or accidentally lowering the classification level.
Observed behavior
Currently, users with edit access to a document can change or downgrade its sensitivity label, and admins lack a built-in toggle to completely block this action.
Before you start

Ensure you have compliance administrator privileges in the Microsoft Purview portal to review and modify your organization's current sensitivity label policies.

Require Justification for Label Downgrades

While you cannot completely block downgrades, you can deter users by forcing them to provide a valid justification before lowering a label's sensitivity.

Microsoft currently does not support completely preventing users from changing or downgrading a sensitivity label. However, enforcing a justification requirement adds a layer of accountability, discourages unnecessary downgrades, and allows security teams to audit user actions.

1
Access the Compliance Portal

Sign in to the Microsoft Purview compliance portal using your administrator credentials.

2
Navigate to Label Policies

Go to 'Information protection' from the left sidebar and select the 'Label policies' tab to view your active policies.

3
Edit the Target Policy

Select the policy you want to modify and click the 'Edit policy' button to adjust its settings.

4
Enable the Justification Requirement

Proceed to the policy settings page and check the box labeled 'Require users to provide a justification to remove a label or lower its classification'.

5
Save and Publish

Review your changes and save the policy. The update will automatically propagate to users' Office applications.

Frequently Asked Questions

What happens when a user downgrades a sensitivity label?

When a sensitivity label is downgraded or removed, the document loses the specific protections associated with the higher-level label, such as encryption, access restrictions, or visual watermarks. If a justification policy is enabled, the user must provide a reason before the downgrade takes effect.

Can I track which users are downgrading sensitivity labels?

Yes, administrators can use the Activity Explorer in the Microsoft Purview compliance portal to monitor label changes, view which user initiated the downgrade, and read the justifications they provided.

Is it possible to force a default sensitivity label on all documents?

Yes, administrators can configure a label policy in Microsoft Purview to automatically apply a default sensitivity label to all new documents and emails created by users, ensuring a mandatory baseline level of data protection across the organization.
