Microsoft Purview Data Loss Prevention (DLP) is extended to preventing Microsoft 365 Copilot from processing emails with sensitivity labels. This feature will allow 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.
