Organisations monitoring the Microsoft 365 Message Center and Roadmap this month gain critical insights into Teams security enhancements, Windows 10 end-of-support preparedness, and evolving AI video capabilities, while navigating important billing adjustments and communications infrastructure fixes.
Top 5 Microsoft 365 Message Center Items in November 2025
November 2025 brings vital security improvements to Teams communications, alongside urgent reminders about the end of support for Windows 10. From enhanced external user identification that strengthens collaboration boundaries to AI-powered video generation becoming available to all Copilot users, these Microsoft Message Center announcements demonstrate Microsoft's commitment to striking a balance between innovation, security, and operational stability.
MC1171840 - Microsoft 365 Copilot App: AI Video Generation Now Available in Create
Microsoft 365 Copilot now offers AI video generation in the Create experience for all Copilot Chat users, including those without a Microsoft 365 Copilot license.
This feature enables users to create videos using natural language and Word, PowerPoint, and PDF files to communicate their ideas effectively.
Capabilities include:
- Create videos using natural language prompts
- Upload unencrypted Word, PowerPoint or PDF files as source material
- Created videos are fully editable
Deployment details:
- General Availability: Early Nov 2025 - Mid Nov 2025 (Web, Windows, macOS)
- No admin action required to enable this feature
- No Microsoft 365 Copilot license is required
MC1162276 - Trust Indicators- A New Way of Representing Users Outside Your Organisation
Microsoft Teams is introducing Trust Indicators. These are visual badges which identify external, guest, or anonymous users, intending to reduce oversharing risks and help users quickly identify external participants.
Beyond badges, Teams is also introducing an alert banner in the message compose box for any chat, meeting, or channel that includes external participants. This banner uses colour-coding to indicate risk level—appearing in neutral grey when external users are present, but switching to red if any users are "External-unfamiliar" or "Unverified".
Deployment details:
- Public Preview: Late Sept 2025 - Late Nov 2025
- General Availability: Late Nov 2025 - Early Jan 2026 (Worldwide, GCC, GCC High, DoD)
- This feature will be turned on by default - no admin action required to enable
- Communicate this change to the helpdesk or support teams
MC1162280 - Prevent/Fix (Detected) Important CAE Policies Causing Calling and Pairing
Issues with Teams Rooms on Android and Teams Phone devices, calling and pairing failures were detected. This was due to
Continuous Access Evaluation (CAE) policies affecting token validity and has significant implications for both users and administrators.
Since Teams recently moved to a new method of acquiring tokens for calling scenarios, CAE policies are now being automatically enforced on resource tokens, resulting in invalid tokens and degraded functionality across Teams devices.
Recommended Actions:
- Review your Conditional Access policies immediately
- Identify policies that may apply to Teams Rooms on Android and Teams Phone devices
- Disable CAE specifically for these device types
- Monitor device calling and pairing functionality following changes
MC1176303 - We're Updating How We Bill for Mid-Term Subscription Changes
Microsoft is updating how it bills for mid-term subscription changes to improve clarity and efficiency in subscription cost management.
Starting November 13, 2025, changes to existing subscriptions, such as adding or removing licenses, cancellations, and upgrades, will be billed the next day instead of at the beginning of the following month. The aim of this is to provide more timely and transparent billing, helping organisations better track and manage subscription costs with real-time invoicing aligned to actual usage changes.
Example: If your account is in Singapore or Italy and you add a license to your subscription on November 13, you will receive an invoice for that additional license on November 14th.
- Organisations with accounts starting with 'G' will be impacted by this change
- No action is required from users - the update will be applied automatically to eligible subscriptions
MC1172531 - Protect your Windows 10 Devices after Microsoft Support Ends
As of October 14, 2025, Microsoft officially ended support for Windows 10, meaning devices will no longer receive security or feature updates, nor technical support from Microsoft.
While Windows 10 devices will continue to operate, the lack of regular security updates significantly increases vulnerability to cyber threats.
Microsoft Defender will continue to provide detection and protection capabilities to the extent possible on Windows 10 and other legacy systems. However, security solutions on legacy systems are inherently less secure and may not receive all new features.
If running Microsoft 365 Apps on Windows 10 devices, the applications will continue to function. However, Microsoft strongly recommends upgrading to Windows 11 to avoid performance and reliability issues. Microsoft will continue providing security updates for Microsoft 365 on Windows 10 for three years after Windows 10 end of support, ending on October 10, 2028.
Recommended Actions:
- Upgrade to Windows 11
- This is the best way to ensure endpoints remain protected and compliant. Devices running Windows 10 will be more vulnerable, even with ongoing security intelligence updates (SIUs).
- This is the best way to ensure endpoints remain protected and compliant. Devices running Windows 10 will be more vulnerable, even with ongoing security intelligence updates (SIUs).
- Extended Security Updates (ESU) program
- If upgrading isn't immediately possible, Microsoft offers ESU for Windows 10. This provides critical and important security updates but does not include new features or technical support. The consumer ESU programme costs $30 USD for one year of coverage.

Top 5 Microsoft 365 Roadmap Items in October 2025
513271 - Microsoft Teams: Chat with anyone who has an email address
Start a chat with anyone who has an email address, even if they're not on Teams. Recipients receive an email inviting them to join your chat session as a guest, enabling seamless communication, file sharing, and calls all within Teams.
This feature eliminates the friction of requiring external collaborators to have Teams accounts or be part of your organisation's directory, dramatically simplifying ad-hoc collaboration scenarios.
Capabilities Include:
- Initiate chats in Teams using only an email address
- External participants join as guests via email invitation
- Full chat, file sharing, and calling functionality
- No Teams account required for recipients
- Rolling Out: November 2025
- Platforms: Android, Desktop, iOS, Linux, Mac

518218 - Microsoft Teams: Consult and Merge a PSTN Caller through DTMF
Meeting organisers will be able to seamlessly consult and merge PSTN callers to active Teams meetings even when callers are behind auto-attendants that require Dual-Tone Multi-Frequency (DTMF) navigation.
This enhancement removes a significant barrier in hybrid meetings where external participants dial in via traditional phone systems with interactive voice response (IVR) menus.
- Rolling Out: December 2025
- Platforms: Desktop, Mac
516571 - Microsoft Teams: Interpreter Agent Support in Teams Rooms on Windows
The Interpreter agent will act as a real-time translator in Microsoft Teams meetings, allowing participants to listen to the meeting in their chosen language with real-time translation, ensuring speaking different languages isn't a barrier to effective collaboration.
This feature will bring powerful language accessibility directly into Teams Rooms environments, enabling truly global collaboration without language barriers.
- Rolling Out: December 2025
- Platforms: Teams and Surface Devices
520772 - Microsoft Purview: Data Loss Prevention to restrict Microsoft 365 Copilot Processing on Content with Sensitivity Labels
Microsoft Purview Data Loss Prevention is being extended to Microsoft 365 Copilot, allowing DLP policies to detect sensitivity labels in enterprise grounding data and restrict access to that content within Microsoft 365 Copilot.
This critical security enhancement ensures that Copilot respects organisational data classification policies, preventing the AI from processing or surfacing highly sensitive content inappropriately.
- Rolling Out: November 2025
- Platforms: Desktop
Why Monitor Microsoft 365 Message Center and Roadmap?
