Introducing Teams Mode for Microsoft 365 Copilot

Microsoft

Oct 27, 2025

Microsoft 365 Copilot is the AI built for work - and work rarely happens alone, instead our best work often results from collaboration. Today we’re introducing Teams Mode for Microsoft 365 Copilot: a simple, secure way to bring your co-workers into your Copilot conversations, turning individual AI chats into group AI chats in Microsoft Teams. Now, the same Copilot you use for individual work supports group work as well. This new capability builds on our investments in collaborative AI, designed to drive productivity in the flow of work. Read on to learn more.

Teams Mode for Copilot

When you’d like to extend your 1:1 Copilot conversation into a group conversation, simply select “start a group chat” in the top-right corner of the Microsoft 365 Copilot app. This creates a group chat in Teams with your colleagues and Copilot, making it easy for others to build on your work. You choose which messages you’d like to bring forward to the group, ensuring any prompts or responses you don’t want to share are kept private. Now by typing copilot in the group chat, each member of the group can request help from Copilot.

You can also add Copilot to any existing Teams group chat, just like adding a teammate, to help your team research, draft, coordinate, and complete tasks with AI. As the team grows, you can add more users to the group chat. This shared chat – complete with the prior prompts and Copilot responses - allows others to pick up right where the work left off.

Launch Demo

Let’s say, for example, you are preparing a strategy document to address a new market opportunity. You can begin in the Microsoft 365 Copilot app using Researcher to gather background such as the market size, key industry trends, and market leaders. Copilot responds with a concise summary, citing relevant sources and surfacing recent data.

Now, here’s where group chat comes in. You can add colleagues from Engineering, Sales, and Finance to help shape the strategy and refine the document, by clicking “Start a group chat in Teams”. Copilot shares the original research context, and each user can engage with Copilot directly while others observe their colleagues’ lines of thinking and Copilot’s responses:

A Sales colleague prompts copilot to summarize go-to-market strategies used by competitors, and Copilot responds with a breakdown of common distribution models and messaging tactics
An Engineering teammate prompts copilot to compare product features across the top three competitors, and Copilot returns a side-by-side comparison with citations
Meanwhile, a Finance colleague asks for an analysis of average list prices and margin benchmarks in the industry, and Copilot provides a summary based on available financial reports

For any Copilot responses that may reference personal memory, Copilot shares a preview to the requestor and waits for their approval before sharing the results with the group. With everyone aligned on the landscape, the team can ask Copilot to generate a first draft of the strategy document based on the discussion so far, then refine it collaboratively in Word. Copilot continues to support the group, responding to new prompts as the strategy evolves. The result is a streamlined, transparent, and collaborative planning process, powered by Copilot but guided by the group. Importantly, when a group chat is created with Copilot each participant’s access to information adheres to existing Microsoft 365 permissions, and the chat respects existing file access controls, ensuring sensitive information remains protected.
