MC937930 - Microsoft Purview | Data Loss Prevention: Restrict Microsoft 365 Copilot using content with sensitivity labels (preview)

Microsoft Purview Data Loss Prevention (DLP) will soon extend to support Microsoft 365 Copilot. DLP policies will be able to identify sensitive documents based on sensitivity labels and exclude processing for Copilot interactions in Microsoft 365 Copilot Business Chat.

The preview does not support alerts, incident reports, and policy simulation. Audit records will be available at a later time after policy management is enabled for organizations. A Microsoft 365 Copilot license and a Microsoft 365 E5 license or equivalent are required to use this feature.

This message is associated with Microsoft 365 Roadmap ID 423483.

When this will happen:

Public Preview: We will begin rolling out mid-November 2024 and expect to complete by mid-December 2024.

We will update this message later to add the plan for General Availability.

This change will be available by default.

What you need to do to prepare:

This rollout will happen automatically by the specified date with no admin action required before the rollout. Review your current configuration to determine the impact for your organization. You may want to notify your users about this change and update any relevant documentation.
