Microsoft announced the introduction of Copilot Cowork, a new capability within Microsoft 365 Copilot designed to move artificial intelligence from answering questions to actively completing work tasks across enterprise applications.
According to Microsoft, Copilot Cowork enables users to delegate work to AI by describing a desired outcome. The system then converts that request into a structured plan that can be executed across Microsoft 365 services, such as Outlook, Teams, Excel, and other productivity tools. The feature draws on signals from across a user’s workplace data, including emails, meetings, messages, files, and business documents.
The company said Cowork is powered by Work IQ, a system that grounds AI activity in workplace context, so tasks can be executed with an understanding similar to that of an employee. Once a task is assigned, Cowork generates a plan and continues executing it in the background while providing checkpoints where users can review progress, modify actions, or pause the process.
Microsoft emphasized that users retain control over the process. Cowork proposes actions and requires approval before applying changes. The system can also request clarification when necessary while continuing to advance the workflow.
The announcement highlights Microsoft’s broader effort to shift Copilot from conversational assistance to task execution within enterprise software environments. Rather than simply generating content, Cowork is designed to coordinate multi-step work processes.
One example Microsoft described is calendar management. Cowork can analyze a user’s Outlook schedule, identify meeting conflicts or low-value commitments, and propose changes to improve focus time. After user approval, it can accept, decline, or reschedule meetings and automatically block time for focused work.
Another use case involves preparing for meetings. Cowork can gather relevant information from emails, meetings, and internal files to produce a full preparation package. This may include a briefing document, supporting analysis, and a presentation deck, while also scheduling preparation time on the calendar and drafting follow-up communications.
The system can also perform research tasks. In one scenario described by Microsoft, Cowork compiles company research by gathering earnings reports, regulatory filings, analyst commentary, and news sources. It then organizes the information with citations and generates multiple deliverables, including an executive summary, a structured research memo, and a workbook with organized financial data.
Microsoft also described how Cowork can assist with cross-functional workflows such as product launches. In those cases, the system can generate competitive analysis spreadsheets, create positioning documents, produce presentation materials, and outline milestones and responsibilities for teams.
The company said Copilot Cowork operates within Microsoft 365’s existing enterprise security and governance framework. Identity controls, compliance policies, and auditing systems apply automatically, while the tasks themselves run in a protected cloud sandbox so they can continue executing even as users move across devices.
Microsoft also revealed that the technology incorporates capabilities developed in collaboration with Anthropic, integrating elements of Claude Cowork technology into Microsoft 365 Copilot. The company said its approach relies on a multi-model architecture that can select the most suitable AI model for different tasks.
Copilot Cowork is currently being tested with a limited group of customers as part of a research preview. Microsoft plans to expand availability through the Copilot Frontier program later in March 2026.
