October 14, 2025
Teams introduces low-latency premium town halls and Silent Test for network readiness, plus a VDI optimization for Teams in Amazon WorkSpaces. It adds screen capture protection and privacy-minded live captions that limit scrollback while preserving real-time transcription.
Introducing a low-latency attendee experience for premium Teams town hall
Previously in a town hall, attendees were typically 20-30 seconds behind the content being presented. With this new update for premium town halls, attendees can watch the town hall at a much lower latency than before.
Silent Test call
Silent Test provides an ability for IT admins to proactively run a synthetic simulation of a Teams call to the subnet to examine network readiness before any issues occur.
New VDI solution for Teams optimization in Amazon WorkSpaces
New VDI solution for Teams introduces a multimedia offloading and optimization solution for Microsoft Teams when running in Amazon WorkSpaces (Personal and Pools). Users of the WorkSpaces Client for Windows can enjoy a high-definition experience in virtual desktops, where audio or video or screensharing are offloaded to the user's device and processed by the SlimCore media engine. This entry applies to WorkSpaces only (AppStream is not supported).
Enhanced meeting protection: Prevent screen capture
To address the issue of unauthorized screen captures during meetings, this feature ensures that if a user attempts to take a screen capture, the meeting window will turn black, thereby protecting sensitive information. This feature will be available on Teams desktop applications (both Windows and Mac) and Teams mobile applications (both iOS and Android). Users joining from unsupported platforms will be placed in audio-only mode to maintain the integrity of the meeting's content.
Limit live captions scrollback (Compliance-safe mode)
Live Captions in Microsoft Teams allow you to follow conversations in real time, making meetings more accessible and inclusive. To improve privacy, captions will now only show recent dialogue (about 5 minutes) when transcription is off, instead of the full meeting history. This means captions are used just for real-time communication, not as a permanent record. If transcription is enabled, captions will display the entire meeting conversation, consistent with Live Transcript. We've also fixed an issue where caption data could be lost when changing the caption position or popping captions in and out. Now, these adjustments won't affect caption data, giving you a more reliable experience. These changes also apply to Real-time Text (RTT), ensuring a consistent and accessible captioning experience across formats.
