  "textContent": "🚨\n\n**Major Update:** This post contains a significant change that may impact your organisation.\n\n**[What and Why]**\n\n**Microsoft Defender for Endpoint (MDE) on iOS** is retiring in-app OS update notifications and recommendations. To improve consistency and reduce duplicate guidance, OS update compliance and enforcement will rely on Microsoft Intune and existing MDM/MAM capabilities instead of Defender in-app experiences. This change simplifies management for administrators and provides a more unified and secure compliance experience across Microsoft security and device management services. Intune driven OS update requirements will remain unaffected by this change.\n\n**[Rollout Schedule]**\n\n  * **Worldwide, GCC, GCCH, DoD:** Mid-July 2026 through late July 2026\n\n\n\n**[Impact on Your Organization]**\n\n_Who is affected_\n\n  * Organizations using Microsoft Defender for Endpoint on iOS\n  * Admins managing device compliance or OS update policies\n\n\n\n _Platforms/Services_\n\n  * iOS\n  * Microsoft Defender for Endpoint\n  * Microsoft Intune\n\n\n\nWhat will happen:\n\n  * The Defender app on iOS will no longer display OS update recommendations or notifications.\n  * OS update compliance and enforcement will rely on Microsoft Intune and existing MDM/MAM capabilities instead of Defender in-app experiences.\n  * Duplicate or conflicting OS update messaging between Defender and Intune will be removed.\n  * This change will be automatically applied during rollout.\n  * After retirement, there is no option to continue using this functionality in _Defender_.\n\n\n\n**[Action Required / Recommendations]**\n\nNo immediate action is required for this change.\n\nTo prepare and ensure a smooth transition:\n\n  * Review your OS compliance and update enforcement policies in _Microsoft Intune_.\n  * Validate existing app configuration policies (for example, OS update notification suppression settings) to ensure they align with this change.\n  * Inform your helpdesk and end users that OS update notifications will no longer appear in the _Defender app on iOS_.\n\n\n\n**[Compliance considerations]**\n\nNo compliance considerations identified. Review as appropriate for your organization.",
