Copilot in Microsoft Teams can summarize chat messages by providing high-level summaries and key takeaways from the conversation it is invoked from. Users can choose to summarize the last 1, 7, or 30 days of conversation. Additionally, users can enter queries through free text Q & A, and Copilot will generate answers based on the chat history, addressing common inquiries like decisions made or open items.

Copilot activates once a transcript is initiated in meetings. It can be set to operate only during the meeting or during and after the meeting, depending on the organizer's preferences. Users can ask questions at any time, and Copilot will generate answers based on the meeting transcript, summarizing discussions, generating action items, and listing unresolved questions.

Copilot in Microsoft Teams does not share user data with third parties, nor does it use user data to train its model. This ensures that your information remains private and secure while using the service.
