Microsoft 365 Roadmap Updates December 2025

M365 News, Microsoft, OneDrive, Sharepoint, Teams, Windows

So Ignite has come and gone and we are back at the grind. Most of which, is seeing the pain, er… I mean opportunities that come to us in the form of M365 App updates. Below is a paste from a specific Copilot curated prompt with my opinions to inform us of all the new stuff coming our way before the year end. Within this post, I do not cover every single app. My aim is to target those apps with the largest impact. Caution, Microsoft can and does change their mind at times on scope/release dates. Do your due diligence should you be in the position of managing end users.

Microsoft is closing out 2025 with a powerful wave of updates across OneDrive, Teams, SharePoint, Copilot, Windows 11, and Microsoft 365 desktop apps. From AI agents and multilingual meetings to security patches and new collaboration tools, here’s everything you need to know.

OneDrive

    A new Copilot button in the OneDrive web interface allows users to summarize, compare, and query documents directly.

  • Copilot Chat Expansion
    Free Copilot Chat is now integrated into Outlook, Word, Excel, and PowerPoint for all Microsoft 365 subscribers.
    • Note, this line item right here is why I wrote this post. Does this mean that Copilot Chat can now see unsecured SharePoint data that you aren’t ready to have it surface? I do not have the answer yet. But be warned!
