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.
Details
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.

When this will happen:
- Copilot Cowork is now available in Frontier.
- General availability will be communicated at a later date.
How this affects your organization:
Who is affected:
- Users with a Microsoft 365 Copilot (Premium) license
- Users enabled for FrontierÂ
- English language only
Prerequisites and controls:
- The tenant must be enrolled in the Frontier program.
- Microsoft‑built agents must be enabled.
- Anthropic must be enabled as a subprocessor (default: on).
- For tenants based in the European Union (EU), Copilot Cowork is off by default due to EU Data Boundary requirements and must be explicitly enabled.
What will happen:
- Users can install Copilot Cowork from the Agent Store in the Microsoft 365 Copilot app and pin it to the left rail.
- Users can describe an outcome in natural language, and Copilot Cowork will:
- Automatically generate a multi-step plan grounded in the user’s Microsoft 365 context
- Coordinate tasks across Microsoft 365 apps such as Word, PowerPoint, Outlook, and others
- Continue work overtime with visible checkpoints and progress tracking
- Copilot Cowork proposes actions and requires explicit user approval before acting on tasks such as:
- Sending emails or Teams messages
- Scheduling, declining, or rescheduling meetings
- Editing or moving files
- Users can pause, adjust, or stop execution at any time and return later to review progress.
- For eligible tenants, the experience is enabled by default and respects existing Microsoft 365 permissions and policies, unless restricted by EU Data Boundary settings.
What you can do to prepare:
- No admin action is required.

Compliance considerations:
| Compliance question | Explanation |
|---|---|
| Does the change introduce or significantly modify AI/ML or agent capabilities that interact with or provide access to customer data? | Copilot Cowork introduces a new Microsoft-built agent that orchestrates multi-step work across Microsoft 365 services using existing customer data, while requiring explicit user approval before taking actions. |
| Does the change provide end users any new way of interacting with generative AI? | Users can describe an intended outcome in natural language and have Copilot Cowork generate and execute a multi-step plan with progress tracking. |
| Does the change add any integration to 3rd party software products? | Anthropic is used as a subprocessor to support Copilot Cowork capabilities and is enabled by default. |
| Does the change include an admin control? | Availability is controlled through Frontier enrollment, agent enablement settings, subprocessor configuration, and EU Data Boundary defaults. |
| Does the change allow a user to enable and disable the feature themselves? | Users can install Copilot Cowork from the Agent Store and can pause, adjust, or stop execution at any time. |
