Summary:
Copilot Cowork is now available in Frontier for Microsoft 365 Copilot Premium users, enabling multi-step task orchestration across apps with user approval and progress tracking. It requires Frontier enrollment, enabled agents, and Anthropic as a subprocessor. EU tenants must enable it explicitly due to data boundary rules.

[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.
