Updated July 27, 2026: We have updated the timeline. Thank you for your patience. [Introduction] Recap without saving transcript provides an alternative now for Copilot users to generate a meeting summary using live meeting context, in case where saving a meeting transcript or recording is not preferred or allowed.
