The September 2025 Windows security update is now available



We are introducing Advanced Agentic AI grading system integrated into the native MDO submission analysis and response workflow. This integration allows for prompt, detailed verdicts with natural language explanations when customers report phishing messages to Microsoft.

Microsoft 365 will introduce new Graph API endpoints designed to empower IT administrators and developers with robust programmatic access to app and agent management across Copilot, Teams, Outlook, and other MetaOS hosts.
Key Features:
• Inventory API: Retrieve a comprehensive inventory of all apps and agents within your tenant, with advanced filtering by type (1P, 3P, LOB, Shared), host (Copilot, Outlook, Teams, Office), last updated date, and more. This enables bulk management, compliance checks, and streamlined governance for large organizations.
• Details API: Access detailed metadata for any specific app or agent, including availability, deployment status, supported hosts, creator information, version, sensitivity, categories, and capabilities (such as Graph connectors, knowledge sources, and plugin actions). This supports auditing, lifecycle management, and integration into existing IT workflows.

New call controls and streamlined transitions enable simple and seamless transfers for Teams Phone users on Android devices.

This feature adds the ability to manage the password used to access the macOS recovery partition. Configuring a recovery OS password prevents users from booting company-owned devices into recovery mode, reinstalling macOS, and bypassing remote management.

Messages in Teams that contain malicious URLs will now be automatically detected, and a warning will be displayed directly on the message.

Agent metadata export in Microsoft 365 admin center includes expanded metadata fields, covering Capabilities, Data Sources, Actions, Created In, and Created By. Enables enhanced visibility for auditing, governance, and lifecycle tracking.

Engage network admins and corporate communicators can mute conversations to remove a thread from distribution in the home feed and in email digests directly from the Engage app in Teams for iOS & Android.

Admins can reassign ownership of shared agents created within the organization through tools such as Copilot Studio or the Microsoft 365 Agents Toolkit. Once reassigned, the new owner will gain full edit and delete permissions, along with access to any files uploaded by the previous owner. The former owner will lose all access, including read rights.
