To help users prepare more effectively for meetings, Microsoft Copilot in Outlook is expanding to support all meetings - including 1:1s. In this update, there will also be new real-time insights that summarize relevant context, tasks, documents, and other resources directly within the meeting event form. Users will also be able to chat with Copilot to prepare more deeply, whether it's confirming action items or learning more about meeting goals.
