Updated April 7, 2026: We have updated the timeline. Thank you for your patience.
[Introduction]
We’re introducing Annotations on Single Window Sharing for Windows in Microsoft Teams meetings, based on customer feedback requesting more focused and privacy‑preserving collaboration. Presenters can now annotate directly on a shared application window without sharing their entire desktop.
This message is associated with Roadmap ID 555239.
[When this will happen:]
- Targeted Release: Rollout begins early March 2026 and is expected to complete by mid-March 2026.
- General Availability: Rollout begins mid-March 2026 and is expected to complete by mid-April 2026 (previously late March).
[How this affects your organization:]
Who is affected:
- Users who present content in Microsoft Teams meetings on Windows
- Meeting participants on Windows, macOS, and mobile devices
What will happen:
- Presenters can share a single application window instead of their full screen.
- Annotations can be started from the presenter toolbar during window sharing.
- Participants can view and contribute to annotations.
- The feature is enabled by default and requires no admin configuration.
- Existing Teams and Microsoft Whiteboard behaviors for annotation storage and access are respected.
- There is no change to background app visibility—notifications and unrelated windows remain private.
[What you can do to prepare:]
- No action is required. The feature will be available automatically as it reaches your tenant.
- Consider notifying helpdesk and end users about the new annotation capability during window sharing.
- Ensure presenters use the Microsoft Teams desktop app on Windows and are on a supported version.
- Review existing internal guidance or training materials related to Teams screen sharing and update as needed.
- Annotations are initiated by the presenter during single window sharing.
- Annotation content follows existing Microsoft Whiteboard storage and retention behavior.
- Presenter support is currently limited to Windows.
[Compliance considerations:]
No compliance considerations identified, review as appropriate for your organization.
