What’s new for Microsoft Teams – December 2025
Every now and then, Microsoft introduces a set of small updates to Teams that end up making a big difference in how we work. December 2025 is no exception. This time, I’m highlighting three features that aren’t related to Copilot but still have the potential to improve productivity and create a stronger sense of connection within organizations.
The first update is a game-changer for Private Channels. For a long time, these channels were limited to chat-only interactions, but that’s about to change. Starting mid-January 2026, apps will be supported in Private Channels, enabling bots, tabs, and message extensions. This upgrade transforms Private Channels into true collaboration spaces, backed by new governance controls. Admins and developers should review policies and update apps to ensure compatibility with channel-level permissions and data compliance.
The second improvement addresses a long-standing pain point: forwarding messages. Until now, forwarding multiple messages meant doing it one by one. With the latest update, you can forward messages in batch, making conversations easier to share. And finally, customization gets a boost with branded reactions. Organizations can now upload custom reaction icons that reflect their brand or event themes, creating more cohesive and on-brand meeting experiences. A simple but powerful way to make meetings feel more connected.
