This message applies to Teams for Windows desktop and Teams for Mac desktop and is associated with Roadmap ID 560055.

[When this will happen:]

[How this affects your organization:]

Who is affected:

Users running Microsoft Teams on hardware‑constrained devices (for example, devices with limited CPU, memory)
What will happen:

Efficiency Mode is enabled by default on eligible devices.
An Efficiency Mode indicator appears in the Teams app title bar.
When enabled:
- Video resolution sent from the user’s camera is dynamically adjusted in meetings.
- The app launches without a pre-selected chat and shows a static image in the message pane.
Users can opt out via Settings > General > “Never use efficiency mode.”

[What you can do to prepare:]
