Microsoft update the prerequisites for Agent 365 once again, with a mid-month change to the Product Terms.

Following the prerequisites added on June 1, 2026 (see our blog post here: https://bit.ly/3SjxSMa), the June 15 update adds further options:

• Microsoft 365 A5
• Microsoft Defender Suite and Microsoft Purview Suite
• Microsoft Defender Suite Edu and Microsoft Purview Suite Edu

A standout point here is that both the Defender AND Purview Suites are required, not just one or the other.

So the (current!) state of play means that alongside Microsoft 365 E5/A5 and Microsoft 365 Business Premium, the Frontline Worker, Education, and Enterprise flavours of the Defender and Purview Suites are all now valid prerequisites. But what about the SMB Defender and Purview Suite bundle? Although not officially listed in the Product Terms, the latest FAQs confirm that you do indeed need it for Agent 365 to work.
