To understand E7, you need the SKU ladder.

Microsoft 365 E3, at $36 per user per month, packages productivity apps, unified endpoint management, and baseline security.

E5, at $57 per user per month, adds integrated cyberthreat protection, XDR, Power BI Pro, and premium compliance capabilities.

Neither tier, however, includes Microsoft 365 Copilot or any structured control layer for AI agents. They are or will be available as add-ons. For example, M365 Copilot comes at $30 per user per month.

E7, priced at $99 per user per month, bundles Microsoft 365 E5, Microsoft 365 Copilot, and the new Agent 365 into a single SKU. It also includes the Microsoft Entra Suite and advanced Defender, Intune, and Purview capabilities. Buying these components separately would cost approximately $102 per user, so the bundling argument is real, if modest.

As agent proliferation accelerates (remember some times ago, with Access application, or the Power Apps proliferation concerns ?), IT and security teams have been flying in a foggy weather.

Agent 365 is the control plane for AI agents, giving IT and security leaders a single place to observe, govern, manage, and secure agents across the organisation. This using the same infrastructure and protections already used to manage people. Think of it as Active Directory for your AI workforce.

In its preview period, tens of millions of agents appeared in the Agent 365 Registry within just two months, with Microsoft itself gaining visibility into more than 500 000 internal agents across the company. The signal is clear: without a control plane, agent sprawl is already happening.

Microsoft frames E7 as priced below the cost of purchasing capabilities “à la carte”, and arithmetically, that’s accurate. But for organisations currently on E3, this represents a jump from $36 to $99, nearly a 175% increase per seat.

For IT architects, the more consequential question is not the licence cost but the readiness of your data foundations, your agent governance model, and your change management capacity. E7 packages the tools, the hard work remains in the hands of the organisations.
