In Brief

• Copilot Cowork is now available worldwide to Microsoft 365 Copilot subscribers.

• Delivers end-to-end task automation, security controls and usage-based pricing.

• Lets IT leaders manage complex workflows and AI costs while maintaining compliance.

Microsoft on June 16 moved Copilot Cowork to general availability worldwide, shifting the AI task engine from preview to production for all Microsoft 365 Copilot subscribers. According to the company, more than half of the Fortune 500 — including Accenture, Avanade, Capital Group, Koch, Ooredoo Qatar and Zurich Insurance — already use the tool.

Cowork executes complex, long-running, multi-tool tasks end-to-end and returns completed results. The GA release introduces usage-based billing denominated in Copilot Credits, a plugin ecosystem and granular cost controls for IT leaders.

Microsoft said Cowork costs 30%–40% less per prompt than Claude Cowork with the Microsoft 365 connector, based on internal testing of 125 runs across 12 prompt types in June 2026.

Microsoft's New Agent Moves Beyond Assistance to Autonomous Task Execution

Cowork shifts Microsoft's AI assistant from answering questions to executing multi-step work across Microsoft 365 — raising new AI governance questions. Tasks include rescheduling meetings, drafting presentations, compiling research and coordinating projects via natural-language instructions.

The Work IQ Foundation

Cowork runs on Work IQ, the intelligence layer atop Microsoft Graph, composed of three parts:

• Data — signals from activity across Microsoft 365

• Memory — habits, preferences, writing style and collaborators

• Inference — connecting signals to anticipate what users need next

Tasks run in a sandboxed cloud environment and continue across device switches without interruption.

Governance & Security Posture

Cowork inherits an organization's existing Microsoft 365 identity controls, permissions and compliance policies, with auditable records of all actions. However, Cowork dynamically selects AI models — including Anthropic's Claude — based on task type, meaning sensitive enterprise data may route through systems an organization did not explicitly evaluate.

Analysts advise keeping compliance workflows, regulated reporting, legal approvals and customer-facing tasks off-limits until observability and rollback tooling matures.
