Microsoft unveils Copilot Cowork in major Wave 3 update
Microsoft has introduced Copilot Cowork as part of the Wave 3 update for Microsoft 365 Copilot. The new feature acts as an AI agent that automatically plans and executes work tasks across multiple applications.
What happened?
Microsoft has announced Wave 3, a large-scale update to Microsoft 365 Copilot, which introduced the new AI feature Copilot Cowork on 9 March 2026. The feature operates as an AI agent that does not merely answer questions or create individual documents, but plans and executes actual work tasks for the user. Copilot Cowork can work across multiple Microsoft 365 programs, analysing schedules in Outlook, compiling briefs, creating presentations, and gathering data for research and financial reports.

It is designed to take over administrative work such as calendar management, competitor analysis, and compiling Excel data, allowing users to focus on strategic tasks.
Who is affected?
The feature primarily impacts businesses and office workers who use Microsoft 365 in their daily operations for scheduling, document management, and report writing. Developers and administrators within organisations are also affected, as AI agents take a more active role in performing tasks in the background.
What else you should know
The Wave 3 update marks a transition where the AI assistant in Microsoft 365 moves from answering questions to more independently executing complex sequences of work tasks for the user.
