December 2025 brings a range of impactful updates across Microsoft 365 solutions, designed to enhance collaboration, productivity, and security.
Key highlights include improved external sharing and conversation tracking in Teams, streamlined scheduling with Outlook polls, advanced security automation through Copilot, and innovative video recaps for meetings.
