Microsoft has announced the general availability of Copilot Cowork worldwide, an AI-powered tool that is designed to automate complex workplace tasks across multiple business applications.
The announcement comes after a three-month preview period under Microsoft’s Frontier Program, during which more than half of Fortune 500 companies adopted the technology alongside firms including Accenture, Avanade, Advance Local, Capital Group, Koch, Ooredoo Qatar, and Zurich Insurance.
According to the tech giant, the organizations have already adopted the tool to automate work that previously required extensive manual work.
“Cowork is the fastest growing feature in the history of our Frontier program, and Cowork has among the highest user satisfaction of any Copilot or agent experience we have shipped,” the company said.
“We learned from what we saw, engaged with you along the way, and used everything we heard to improve quality and add new features, including model choice, extensibility through plugins, and new cost management controls,” it added.
Unlike other AI assistants that generate recommendations or drafts, Microsoft says that Copilot Cowork is actually designed to execute long-running, multi-step assignments from start to finish.
The platform is built on five key pillars, which include cloud hosting, Work IQ integration, enterprise-grade security and compliance, multi-model support, and lower operating costs.
“When comparing the cost per prompt between Copilot Cowork and Claude Cowork with their Microsoft 365 connector, testing showed that Copilot Cowork, on average, was 30-40% cheaper,” the company said.
The platform is currently running on Anthropic models, including Opus 4.8 and Sonnet 4.6, while customers participating in Frontier can also access GPT-5.5. Microsoft is also expected to release a new model, Cowork 1, which will offer lower-cost and enterprise-focused AI capabilities.
Copilot Cowork will require organizations to have a Microsoft 365 Copilot User Subscription License, after which customers will pay based on usage through a system called Copilot Credits.
The company has also introduced new cost management features that will allow administrators to set spending limits, allocate budgets, configure usage alerts, and monitor consumption at the tenant, group, and individual user level. The tool will help businesses manage their spending.
Unlike traditional AI assistants that primarily generate summaries, recommendations or draft content, Copilot Cowork is built to carry out extended business processes on behalf of users.
The Microsoft 365 Copilot feature can work across documents, applications, organizational data sources and connected services to complete multi-step tasks with minimal human intervention.
Microsoft also emphasized security and compliance, saying Cowork prompts, responses and generated artifacts flow through existing Microsoft 365 controls. The GA release includes support for audit logs, Data Security Posture Management, eDiscovery, Insider Risk Management and sensitivity label inheritance, with Data Loss Prevention support coming later.
Separately, Microsoft announced the public preview of the Agent Identities Asset Connector for Microsoft Sentinel, a move aimed at giving security teams better visibility into the growing population of AI agents inside enterprise environments.
The connector is designed to ingest agent and agent blueprint identity data into Sentinel so security teams can understand ownership, analyze relationships and correlate agent identities with activity and risk signals.
Microsoft describes the connector as a way to give defenders a central view of agent identities, which is likely to become more important as organizations move from experimenting with AI agents to deploying them across business processes.
