As of June 1, 2026, Microsoft has introduced Microsoft 365 E5 as a new license prerequisite for new Microsoft Agent 365 purchases.

For new Agent 365 purchases as of June 1:

  • Enterprise customers must have Microsoft 365 E5.
  • Frontline worker (FLW) users must have Microsoft Defender and Purview (F5 level).
  • Small and medium-sized business (SMB) customers must have Microsoft 365 Business Premium.

Customers without these prerequisites will have restricted access to certain Agent 365 capabilities. This update will have no impact on Microsoft 365 E7 customer engagements, as Microsoft 365 E7 includes Microsoft 365 E5, Agent 365, Microsoft 365 Copilot, and Microsoft Entra Suite.
