Microsoft Purview Data Loss Prevention (DLP) will soon extend to preventing Microsoft 365 Copilot from processing emails with sensitivity labels. This feature will allow existing or new DLP policies to provide detection of sensitivity labels in emails as enterprise grounding data and restrict access of the labeled emails in Microsoft 365 Copilot chat experiences. This feature only works for emails sent on or after January 1, 2025.

The preview does not support alerts, audit records, and policy simulation.

A Microsoft 365 Copilot license is NOT required to access this feature.
