Microsoft has announced the launch of “Copilot Cowork,” a new cloud-powered AI automation tool designed to operate across Microsoft 365 applications, developed in collaboration with Anthropic, which provides the underlying technology of Claude Cowork. This feature enables users to delegate complex, multi-step tasks that span various Microsoft apps such as Outlook, Teams, and Excel, enhancing operational efficiency. The rollout is part of a broader update, termed “Wave 3,” which integrates Anthropic’s Claude models into the overall Copilot experience and emphasizes strong enterprise security by utilizing existing identity and compliance frameworks. Currently in Research Preview, Copilot Cowork is set for a wider release through Microsoft’s Frontier program in late March 2026.
Anthropic: Anthropic develops the Claude family of AI models with a focus on safety and reliability for complex tasks. In early 2026, it released and updated Claude Cowork desktop applications for Mac and Windows, enabling AI-driven workflow automation through local file access and plugins for services like Google Drive and Slack. Its technology powers the core execution capabilities of Microsoft’s newly announced Copilot Cowork within the M365 ecosystem.
Microsoft: Microsoft is a leading provider of cloud infrastructure through Azure and enterprise productivity applications via Microsoft 365. It recently launched Copilot Cowork as part of Wave 3 updates to Microsoft 365 Copilot, a cloud-based AI agent that autonomously plans and executes multi-step tasks across apps like Outlook, Teams, Excel, and PowerPoint. The product integrates Anthropic’s Claude technology to enhance agentic capabilities while operating within M365’s security and governance boundaries.
Satya Nadella: Satya Nadella is the Chairman and CEO of Microsoft, overseeing advancements in AI and cloud computing. He promoted the Copilot Cowork launch on X, emphasizing its ability to transform user requests into executable plans grounded in M365 work data and executed across apps. This announcement highlights his strategy to evolve Copilot from conversational AI to an autonomous execution layer for enterprise productivity.
Charles Lamanna: Charles Lamanna serves as President of Business Applications and Agents at Microsoft, directing innovation in AI-powered business tools. In the Copilot Cowork blog post, he described it as enabling Copilot to move beyond chatting to taking action on complex tasks with user oversight. His leadership drives agentic features into individual Office apps and the broader M365 platform.
Partnership: Microsoft collaborated closely with Anthropic to integrate Claude Cowork technology into Copilot Cowork for agentic AI in M365.
Model Choice: Copilot now offers Anthropic’s Claude models in mainline Chat alongside other providers, adopting a multi-model approach for optimal task performance.
Enterprise Security: Copilot Cowork leverages M365’s existing identity, permissions, and compliance policies, with all agent actions fully auditable.
