MC1431377Microsoft Defender XDRstayInformedUpdated: 6 August 2026

Microsoft Defender for Office 365's AIR experience will add a manual refresh button, replacing auto-refresh, and simplify investigation names by removing email subjects and UPNs. These changes improve performance, reduce network activity, and support data minimization. No admin action is required, but workflow updates are recommended.
