What’s new for Microsoft Teams – September 2025
September kept the same fast pace we saw during the summer, delivering a mix of AI-driven features and subtle UI improvements that aim to make collaboration smoother and more productive. Microsoft continues to invest heavily in Copilot-powered experiences, and this month’s updates show how AI is becoming an integral part of everyday teamwork.
The biggest highlights include the introduction of Channel Agent , an AI assistant that brings intelligence to Teams channels, and the Facilitator Agent, now generally available to enhance meeting experiences. Alongside these, a small but impactful UI tweak makes it easier to track forwarded messages and maintain context in conversations. These updates may seem different in scale, but together they reflect Microsoft’s focus on simplifying workflows and helping teams stay aligned.

Rolling out from September to November 2025, the feature requires admin activation during preview and will be on by default at general availability. It scans URLs using Microsoft Defender reputation data.
Microsoft Teams will block messages containing unsafe, weaponizable file types in chats and channels starting September 2025 (targeted release) and November 2025 (general availability). Admins can enable this protection via Teams Admin Center or PowerShell. Blocked files include executables and other risky formats to reduce malware risks.
Teams Rooms on Android will dynamically resize video tiles in Gallery view based on room occupancy, matching the Windows experience.

Microsoft Teams will enable admins to assign custom external access policies by user or group, allowing specific control over which external domains they can interact with. This feature, available from September 2025, supports five policy options and will be manageable via PowerShell initially, then through the Teams admin center UI.
Today, IT admins in the Teams admin center can view the permissions requested by an app or agent—these permissions define what organizational data the app can access. This feature enhances that experience by showing the risk rating of each permission and the overall privilege level of the app or agent, helping admins better secure organizational data and make faster, more informed approval decisions.
It’s easier for admins to enable the benefits of intelligent audio and video and Copilot for users in Teams Rooms through a new user interface and admin settings. These new settings, on the device and in the Pro Management portal, simplify configuration and remove the requirement to use PowerShell, offering improved visibility across rooms.
The new page in the Pro Management portal provides proactive recommendations based on your organization’s environment and upcoming events that can impact devices, such as support or certification expirations. Admins are prompted to update device and account data enabling rich insights from the portal, and guidance based on space and device usage data is coming soon. This feature helps admins maintain smooth operations and plan and budget efficiently. At least one Teams Rooms Pro or Teams Shared Devices license is required for access.

Administrators using the Microsoft 365 admin center and Teams admin center who manage agents and apps that work across Teams, Outlook and the Microsoft 365 copilot will be able to apply their changes consistently across all these surfaces. Before this update, changes made through the Integrated Apps section in the Microsoft 365 admin center would only affect these apps on Outlook and the Microsoft 365 copilot; similarly, changes made in the Teams admin center would exclusively affect Teams. With this change, app and agent availability will be unified across Teams, Outlook and Microsoft 365 copilot.
Missed many messages? Copilot will automatically generate a summary of the new messages in a chat conversation, so you can catch up quickly without reading every message.
Today, IT admins in the Teams admin center can view security and compliance data for apps and agents that are Microsoft 365 certified or publisher attested.This enhancement expands that visibility to include apps and agents that are not certified or attested.Where available, this data is sourced from Microsoft Defender for Cloud Apps (MDA) and helps admins more easily and quickly evaluate whether an app or agent meets their organization’s trust requirements.
Microsoft Defender for Office 365 will introduce message warnings in Microsoft Teams for messages containing URLs flagged as Spam, Phish, or Malware. Starting with a public preview in September 2025 and general availability in November 2025, warnings will appear for both recipients and senders, enabled by default and manageable via Teams Admin Center.
Microsoft Teams is enhancing the Profile Card organization chart on Windows Desktop, Mac, and web with improved UI, easier navigation, centered individual view, fewer clicks, and new navigation buttons. Rollout starts late October 2025, enabled by default, requiring no admin action.

Microsoft Teams now supports SlimCore-based optimization for Citrix VDI, offering better performance and new features. Admins must update Citrix Studio policies to whitelist virtual channels (MSTEAMS, MSTEAM1, MSTEAM2) and deploy the Citrix Plugin. WebRTC optimization will be deprecated in the future.
Teams Town Hall now matches Teams Live Events in features, offering enhanced controls and attendee experiences. Users are encouraged to transition to Town Hall, as it supports large-scale virtual events and will replace Live Events in the future. Enable IT policies to prepare for this change.

Agents & bots in group chats will now be able to authenticate through Entra. When an app requests a user’s Entra token in a group chat, if that user does not have the app installed or Entra consent, they are sent a targeted message. This targeted message is only visible to that user. This message serves two purposes: to ask the user to install the Teams app personally and to open the Entra permission consent dialog. Once both requirements are met, the app can leverage Entra for the requested permissions (e.g., Graph).
When in a meeting with another Teams Rooms on Windows that has multiple cameras, you can switch camera views in that room via the participant panel on the console, or video tile on a touch board, to optimize your views.
A new Recommended Actions page will be added to the Teams Rooms Pro Management portal’s Analytics & Reports section by late November 2025, providing IT admins with proactive device and account recommendations. It requires Teams Rooms Pro or Shared Devices licenses and offers future space and usage guidance without affecting end users.

Facilitator can help users manage tasks and create documents during meetings. In addition to the tasks that the agent is automatically capturing during the meeting, users can ask Facilitator directly through the meeting chat to create, edit, and assign tasks, which sync to Planner. For tasks related to document creation, users can assign to Facilitator and it will draft the document based on the meeting discussion. Users can also ask the agent to create a draft document on a topic discussed in the meeting.
With AI workflows in the Workflows app for Teams & SharePoint document libraries, you can build custom AI-powered templates to automate complex tasks and streamline daily operations. Admins can enable this feature to equip users with intelligent automation tools that make managing work more efficient and intuitive.
Channel agent works alongside you and your team to help you manage projects. It can create status reports, send emails, schedule meetings, co-author documents, and answer questions. Channel agent understands context from meetings, chats, and files, and uses that knowledge to help you move work forward. It’s designed to save time, reduce manual effort, and make collaboration more intelligent.
Microsoft Teams introduces Channel Agent, an AI-powered assistant for each channel that summarizes conversations, drafts status reports, assigns tasks via Planner, and answers questions. Available in public preview from mid-September 2025, it requires specific Microsoft 365 and Copilot licenses and has limitations on channel types and languages. Admins can manage auto-creation settings.

The enhanced “Manage what attendees see” experience enables organizers to take their Town hall presentations to the next level. Organizers and presenters can apply layouts, backgrounds, theme colors, and name tags to deliver events that are polished, professional, and highly engaging. This feature is available to organizers with a Teams Premium license.
We’re expanding the capability to require explicit consent for recording and transcription to include 1:1 calls in Microsoft Teams. A new setting in the Teams Calling policy allows admins to enforce this requirement before recording or transcription can begin. When a user with the policy initiates recording, transcription, or both in a 1:1 call, the other participant is automatically muted, with their camera and content sharing turned off. The participant will see a prompt asking whether they consent to be included in the recording and transcription.
Cloud IntelliFrame, an AI video enhancement feature, is now available on Teams Rooms for Android with a Teams Rooms Pro license starting mid-October 2025. Administrators must enable it manually via the Teams admin console, with no default activation or changes to existing policies.

IT administrators for Gov cloud customers now have the ability to access detailed logs for both the “Give and Take Control” and “Screenshare” features. These logs will provide comprehensive information, including the names and timestamps of the individuals involved in each action. Specifically, the logs will indicate who initiated or received control, as well as who started the screenshare session, along with the corresponding timestamps and names. This enhancement ensures greater transparency and accountability for all control and screenshare activities. Accessible in Teams Admin Center. Available for GCC, GCC-High, and DoD cloud environments.
Bring the apps your team relies on—tabs, bots, and message extensions—directly into Shared Channels in Microsoft Teams.
