Learn about the Microsoft 365 Copilot policy location (preview)
Microsoft Purview Data Loss Prevention (DLP) can help you prevent items that have specific sensitivity labels applied from being used in the response summarization to prompts in Microsoft 365 Copilot (preview). You do this by creating DLP policies that use the Microsoft 365 Copilot (preview) policy location with the Content contains > Sensitivity labels condition to exclude items from being processed. Identified items will still be available in the citations of the response, but the content of the item won't be used in the response.

They want to minimize the risk of General Data Protection Regulation (GDPR) data being included in Microsoft 365 Copilot summaries and also exclude private information from summaries. They plan to create a DLP policy that uses the Microsoft 365 Copilot (preview) policy location with the Content contains > Sensitivity labels condition to exclude items that have the Personal sensitivity label from being processed in the response summary and also to exclude items that have the Highly Confidential sensitivity label from being processed in the response summary.
