Microsoft 365 E7 — The Frontier Suite
Microsoft's newest and most advanced plan, built for the age of AI agents.
E7 combines everything in E5 with Microsoft 365 Copilot and enterprise-grade AI agent governance — bundled into a single license and a single renewal cycle.

Why organizations choose E7:

Best for: Enterprises ready to make AI a core part of their infrastructure, with a genuine need for deep identity governance and agent oversight — not just standard Office and security needs.
