Microsoft has announced Copilot Cowork, a new feature for Microsoft 365 Copilot designed to carry out tasks across workplace applications such as Outlook, Teams, Excel, and shared files.
Microsoft CEO Satya Nadella shared the announcement on X on Monday, describing Cowork as a system that can take a request from a user and turn it into a series of actions across their work tools.
“When you hand off a task to Cowork, it turns your request into a plan and executes it across your apps and files, grounded in your work data and operating within M365’s security and governance boundaries,” Nadella wrote.
