Microsoft embarks on Frontier Transformation with Microsoft 365 Copilot Wave 3 and Anthropic AI partnership to expand AI model diversity in Microsoft Foundry

The announcement of Microsoft Copilot Cowork, driven by Anthropic AI partnership, sounds the company’s next major leap in enterprise AI. With Wave 3 of Microsoft 365 Copilot, the company is transitioning from traditional AI assistance into deeply embedded agentic capabilities. The timing here aligning with significant momentum as Microsoft reported reaching 15 million paid seats in early February 2026.

Microsoft is entering a new phase of enterprise AI with Microsoft 365 Copilot Wave 3, introducing Copilot Cowork, deeper agentic AI capabilities, and expanded model diversity through its Anthropic partnership. This update marks a shift from AI that assists with tasks to AI that executes real work across Microsoft 365 securely, transparently, and at enterprise scale.

Wave 3 is not just another feature release. It formalizes agentic AI as a core design principle of Microsoft 365 Copilot and introduces the governance, orchestration, and licensing required for enterprise AI adoption.

This article explains what is new, how Copilot Cowork works, when Copilot Cowork will be available, and what organizations should consider as they prepare for large scale AI agents.

Microsoft’s March 2026 updates represent one of the most significant shifts in the Copilot ecosystem to date. Rather than a routine feature release, the company unveiled a coordinated set of advancements that formalize agentic AI as a core part of Microsoft 365.

These announcements include:

  • Wave 3 of Microsoft 365 Copilot – A major evolution that shifts Copilot from prompt‑based assistance into agentic, multi‑step, long‑running execution powered by Work IQ and multimodel reasoning.
  • Expanded model diversity available today – Anthropic’s Claude models and next‑generation OpenAI models are now integrated directly into mainline Copilot experiences.
  • General availability of Agent 365 on May 1 – Priced at $15 per user/month, Agent 365 becomes the enterprise control plane for managing, securing, and governing AI agents at scale.
  • General availability of Microsoft 365 E7 – The Frontier Suite on May 1 Offered at $99 per user/month E7 bundles Copilot, Agent 365, Entra identity tools, and advanced Microsoft 365 E5 security capabilities to support full‑scale frontier transformation.

Copilot Wave 3: A Multi-model Agentic System

With Wave 3, Microsoft 365 Copilot moves beyond single prompt responses and into long running, multi step execution. Copilot can now plan work, orchestrate actions across apps, and deliver finished outputs without users needing to manually guide every step.

This shift is powered by:

  • Work IQ, Microsoft’s intelligence layer
  • Multi model AI, including OpenAI and Anthropic AI
  • A new class of AI agents embedded directly into Microsoft 365
 

Microsoft refers to this evolution as Frontier Transformation, where people and AI operate together across the enterprise with intelligence and trust.

Wave 3 brings these major changes across the Microsoft 365 ecosystem:

  • Copilot Cowork, a new agentic experience
  • Deeper multi‑model intelligence, including Claude and new OpenAI models
  • Agentic capabilities inside Word, Excel, PowerPoint, and Outlook
  • Chat‑first creation and execution through agents in Copilot Chat

 

Work IQ is the intelligence layer of Microsoft 365 Copilot in charge of personalizing the AI tools to users and their organizations.

To enable it to act as the ‘brain’ of Microsoft’s AI foundation, Work IQ is comprised of three tightly woven layers: Data, Context, and Skills & Tools.

Microsoft 365 Copilot incorporates top tier AI models from multiple providers directly into the Copilot experience. In Copilot Chat, users can choose between foundation models from OpenAI and Anthropic, with additional advanced models from other partners coming soon. This allows users to benefit from powerful reasoning and multi‑step capabilities as part of their everyday Copilot workflow, enhanced by Work IQ’s contextual understanding. Copilot automatically selects the most appropriate model for each task, while still giving users the flexibility to pick the model that works best for their needs.

What is Agentic AI?

Agentic AI describes AI systems that do more than generate content.

These agents can:

  • Understand objectives
  • Break work into steps
  • Execute tasks over time
  • Coordinate actions across tools
  • Pause, adapt, or stop based on user guidance

In Microsoft 365, agentic AI shows up through Copilot agents, with Copilot Cowork as the flagship execution agent.

Copilot Cowork

The highlight of this next evolution is Copilot Cowork. Copilot Cowork is the execution agent introduced in Wave 3 and was built by integrating the technology that powers Anthropic’s Claude Cowork directly into Microsoft 365 Copilot.

Microsoft emphasizes that this integration is part of its broader multi‑model approach, where Copilot chooses the best model be it Claude, OpenAI, or Microsoft’s own, based on the specific task.

What Copilot Cowork Does:

  • Executes long‑running, multi‑step work
  • Uses Work IQ to understand emails, meetings, files, chats, and data
  • Breaks complex tasks into steps that unfold over minutes or hours
  • Coordinates actions across Microsoft 365 apps
  • Provides transparency, with checkpoints to review, guide, or stop progress
  • Runs entirely inside Microsoft’s security, identity, and governance boundaries

These capabilities are enabled by a sophisticated orchestration framework that selects the best model or Microsoft built agent for each task.

As Richard Swaisgood, Director of Security and Identity Management at Managed Solution, puts it, “Microsoft 365 Copilot is built on top of large language models, many of which originated from OpenAI, including different versions of ChatGPT.

When you ask Copilot a question, you’re really interacting with an orchestration layer, it plans the request, decides which systems or agents need to be involved, and delivers the response without exposing that complexity to the user.

Behind the scenes, Copilot sends tasks to Microsoft’s MCP tools and first‑party agents, and through external orchestration, routes requests to models like Claude or other third‑party services”.

Examples of Copilot Cowork in Practice

  • Preparing for a customer meeting by gathering context, scheduling prep time, and generating briefing documents and slide decks
  • Reorganizing an Outlook calendar to protect focus time
  • Creating competitive analysis and presentation materials ahead of executive calls

When With Copilot Cowork Be Available?

Copilot Cowork is available through Microsoft’s Frontier program.

To enable it:

  • Admins access Microsoft 365 Admin Center
  • Navigate to Copilot, then Settings, then Frontier
  • Enable Anthropic as an approved AI subprocessor

Availability is expanding through 2026 as part of the Wave 3 rollout plans.

Evolution of M365 Copilot Inside Word, Excel, PowerPoint & Outlook

Before Wave 3, most AI tools treated content creation as a single-action task. Meaning they could produce a document but didn’t handle things like maintaining context across tools, in-app revisions, following organizational templates, and so on. With Wave 3, however, Copilot is now deeply integrated into Word, Excel, PowerPoint, and Outlook, enabling Copilot to:
  • Refine and update existing Word docs
  • Improve Excel spreadsheets with real formulas
  • Create PowerPoint slides that match organizational styles, layouts, and brand kits
  • Draft, rewrite, and finalize Outlook emails
All edits happen inside the app, remain reviewable and reversible, and follow the native behavior of each tool. Microsoft clarified that what was once called “Agent Mode” in preview isn’t a separate mode anymore but is now a core element of Copilot Wave 3’s design. These enhanced in‑app experiences are generally available in Word and Excel today, with PowerPoint and Outlook rolling out next.

Agents in Copilot Chat

Wave 3 also brings agentic capabilities to Copilot Chat, which Microsoft calls the starting point for conversational work.

In chat, you can now:

  • Create documents, spreadsheets, and presentations
  • Schedule meetings
  • Draft and send emails
  • Trigger end to end workflows

Chat is also where the broader ecosystem comes together for:

  • Word, Excel, PowerPoint, and Outlook agents
  • Dynamics 365 insights
  • Power Apps integrations
  • Third-party partners like Adobe, Monday.com, and Figma

This makes Copilot Chat an operational hub for moving from an idea, to planning, to execution.

Agent 365

Agent 365 was also announced as a new control plane for AI agents within their infrastructure to give IT leaders one place to:
  • Observe agents
  • Secure agents
  • Govern agents
Microsoft stated in their announcement: “Agent 365 extends the management, security, and governance processes organizations already use for employees to agents, so they can stay in control as agents become part of daily work”. Essentially, the company is streamlining AI management by applying the proven user-management models to the AI agents themselves. Using integral Microsoft solutions like Microsoft Admin Center for AI agent management and notable Security solutions such as Micfosoft Defender, Entra, and Purview for AI agent governance. General availability for Agent 365 will be set for May 1st at a price point of $15/per user/per mo.
