What Is Next: E7, Agent 365, and the Researcher

Post 14 of 14 — Series Close

Introduction

Cowork is one feature inside a larger shift. Microsoft 365 E7 — the new Frontier Suite tier — bundles Cowork-class capabilities with an enterprise control plane for AI agents. This post sketches the immediate horizon, sticking to what is publicly documented today.

The Near-Term Horizon

Microsoft 365 E7 — the Frontier Suite. Generally available 1 May 2026 at $99 per user per month. E7 brings together:

• Microsoft 365 E5 — productivity, security, identity, and compliance foundation.
• Microsoft Entra Suite — adaptive identity and network access controls.
• Microsoft 365 Copilot — including Cowork as a Frontier preview.
• Agent 365 — the control plane for AI agents.

E7 is positioned as a unified enterprise AI platform rather than a collection of separate products. Pricing represents a 65% increase over E5 — the value case rests on Cowork-class capabilities and Agent 365 governance, not on individual app features.

Agent 365. Agent 365 extends Microsoft’s existing user-management infrastructure to AI agents — central management, identity, security, and compliance for agents at scale. It generally available 1 May 2026 alongside E7. For organizations planning to use multiple agents (built in Copilot Studio, custom agents, third-party agents, and Cowork itself), Agent 365 is the management layer that keeps governance consistent.

Researcher with Critique. The Researcher agent’s Critique capability — one model draft and a second model from a different provider’s review — produces measurable quality improvements. Microsoft reports a DRACO benchmark score of 57.4 for Researcher with Critique, a 13.8% improvement over single-model approaches. The Model Council feature exposes some of this multi-model orchestration to administrators and advanced users.

Multi-model orchestration as a pattern. Cowork’s combination of Anthropic Claude and OpenAI models, with routing managed by Microsoft, is the prototype for how Microsoft expects agent platforms to evolve: the best model per task, governed within the tenant, invisible to most users by default.

What to plan for in the next phases:

• General availability of Cowork — no firm public date yet. Treat preview content as pilot input, not production scope.
• Agent 365 adoption — model your agent inventory now, even if you have only Cowork plus a few Copilot Studio agents.
• Custom skill libraries — start a SKILL.md library for your team in OneDrive (post 5). When organizational skill sharing arrives, you will have curated content ready.
• Workforce model — train people on prompt design, approvals, and oversight. These are the durable agentic-AI skills.

The honest framing. Cowork is not finished. The skill set will grow, the regional availability will expand, Agent 365 will mature, and audit-log coverage will deepen. Teams that win are running structured pilots now, not waiting for GA.

Series Recap

Across 14 posts: enabled Cowork, navigated Anthropic governance, toured 13 built-in skills, built custom skills with SKILL.md, worked through every skill family, set up approvals and the Tasks view, framed three-zone governance, and faced the limits honestly. That is the working set for a credible Cowork rollout today.

Takeaway

Start small. Build one custom skill. Run one scheduled briefing for two weeks. Pilot one document workflow with one team. Compound from there. The Frontier preview rewards organizations that show up with real use cases, not slide decks.
