What's New in M365 Copilot in Oct 2025

There were a lot of new interesting new capabilities being released into M365 Copilot in the month of Oct 2025.  Here are the ones that caught my eye:

• New Session Persistence Enhancements: Ensures users can seamlessly continue conversations when navigating away from a chat session.
• Chat GPT-5 will become the new default model for Copilot Chat.  Currently, you must select it.
• Microsoft Teams Audio Recap is being released.  This gives users the ability to get pod-cast style audio recaps of meetings they select in newscast, executive or casual formats.  You no longer have to sit there and read tons of recaps, you can now listen to the recaps on your drive home!
• Have Copilot draft meeting agendas based on when the meeting is, the attendees, title and users meeting inputs.  Copilot will leverage all your M365 Copilot data in email, chat, and documents and then create an agenda for you.
• Copilot Chat Capabilities with Exchange Online Calendar: 
• Search a calendar based on meeting organizers making it super easy to get all meeting information and summaries.
• Seach calendars that you have been delegated access to which is great for executive assistants to pull information about meetings.
• Search calendars based on meeting categories like title, date, time and location.
• When opening an Office file on a mobile device, you can use Copilot Chat in the file “preview” which streamlines the user experience to ask questions.
