Teams Live Events dies June 30 — migrate now. Exchange Server OWA has an active XSS CVE. Meanwhile, Purview ships posture reporting, Copilot Studio goes fully agentic with computer-use GA, and Entra tackles shadow tenant sprawl.
CVE-2026-42897 demands immediate patch action on all on-prem Exchange deployments, while Teams Live Events hits its June 30 retirement deadline — but this week also delivers real capability unlocks across AI agent governance, Purview posture reporting, and Entra multi-tenant visibility.
Two hard June deadlines, hotpatch going default across all eligible devices, and Agent 365 is now the live control plane for AI governance. This week has teeth.
