[Introduction]
Copilot Cowork is now available in Frontier. Copilot Cowork enables users to orchestrate complex, multi-step work across Microsoft 365 without switching between apps. Copilot Cowork moves beyond answering questions to turning intent into execution by automatically generating plans, coordinating work across emails, meetings, messages, files, and data, and carrying tasks forward with visible progress and user control. This update reflects customer feedback to reduce manual coordination for real work while maintaining enterprise-grade security, privacy, and controls.
