For business users signed in with a Microsoft Entra ID, Microsoft 365 Copilot Chat offers limited AI-powered chat with enterprise data protection. While Copilot Chat uses public web data for tasks such as research and analysis, it doesn’t integrate with Microsoft 365 apps or organizational content such as files, emails, or chats.
