Microsoft 365 Copilot Cowork moves beyond chat-based AI responses by acting as an autonomous agent—an AI that can perform multi-step tasks on your behalf across Outlook, Teams, Word, Excel, and other Microsoft 365 services. Cowork is built on top of Work IQ, Microsoft's intelligence layer that reads your emails, meetings, files, and organizational data to provide context for actions. As of May 2026, Cowork is available through the Frontier preview program and has expanded to include mobile support, custom skills, plugins, and integration with Agent 365. Access requires a Microsoft 365 Copilot license and enrollment in the Frontier early-access program.
