Microsoft 365 Copilot respects Microsoft 365 permissions (“permission trimming”). This means it can only access and summarize content you are authorized to view. Therefore, Copilot cannot answer questions about Teams meetings you are not invited to (and otherwise don’t have access to), making statement 1 No.

Copilot can summarize and answer questions about Teams artifacts you do have access to—such as chat messages, channel posts, and meeting content (for example, transcripts, notes, recordings, and meeting recap details when available). That makes statement 2 Yes.

Copilot can also help you prepare for your schedule by summarizing upcoming meetings you’re invited to, using calendar and meeting context (subject, time, participants, related emails/files, and available agenda/notes). This supports planning and prioritization for the week ahead, so statement 3 is Yes.
