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
Microsoft describes Wave 3 as the point where Copilot becomes much more than a generative assistant. Meaning that Copilot is no longer limited to generating a single output or responding to a prompt but can now participate in work that unfolds over time, grounded in the full context of your files, communications, and organizational relationships.
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
Before we dive into the specific announcements it’s important you to understand Microsoft’s Work IQ. 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 Skils & Tools.
