Microsoft just added a licensing prerequisite to Agent 365. From 1 June 2026, new purchases need Microsoft 365 E5 underneath them. If Agent 365 is on your radar, it is worth checking what you are on before you plan for it.
In short: new Agent 365 purchases now need a foundation licence first. Enterprise customers need Microsoft 365 E5, smaller businesses need Microsoft 365 Business Premium, and frontline workers need Microsoft Defender and Purview at the F5 level.
What changed
Effective 1 June 2026, Microsoft introduced a new licence prerequisite for new Agent 365 purchases. What you need depends on the kind of user:
- Enterprise users need Microsoft 365 E5.
- Small and medium-sized businesses need Microsoft 365 Business Premium.
- Frontline workers need Microsoft Defender and Purview at the F5 level.
Without the prerequisite in place, customers may not have access to certain Agent 365 capabilities.
Why Microsoft did this
Agents act on your data and carry out work on your behalf, so the security, identity, compliance and management foundation matters more than ever. The prerequisite makes sure that foundation is in place before an agent goes to work, rather than bolted on afterwards. It is the same principle we apply to any automation: get the governance right first.
What it means for you
If you are considering Agent 365, check your current Microsoft 365 plan first. You may already have what you need, or you may need to step up to E5 or Business Premium. One useful exception: Microsoft 365 E7 already includes E5, Agent 365, Microsoft 365 Copilot and the Entra Suite, so if you are on E7 you are covered.
This is a prerequisite, not a price rise on Agent 365 itself. It does affect the real cost of adopting it, so it is worth factoring in early rather than at the point of purchase.
