Microsoft Teams: Annotations on single window sharing for macOS [MC1288528]

Message ID: MC1288528

[Introduction]

We’re introducing annotation support for single application window sharing on macOS in Microsoft Teams. Presenters can now share a single application window and enable meeting participants to annotate directly on top of that content—without sharing their entire desktop. This update helps protect privacy while enabling more focused and interactive collaboration during training sessions, workshops, and client meetings.

This message is associated with Microsoft 365 Roadmap ID 559611.

[When this will happen:]

• Public Preview (Worldwide): We will begin rolling out in early May 2026 and expect to complete by mid-May 2026.
• General Availability (Worldwide): We will begin rolling out in mid-May 2026 and expect to complete by late May 2026.

[How this affects your organization:]

Who is affected:

• Teams users on macOS who present or participate in meetings using screen sharing
• Microsoft 365 admins managing Teams meeting experiences

What will happen:

• Users on macOS will be able to annotate directly on a shared application window (for example, a document, browser tab, or design tool).
• Participants can use drawing and highlighting tools to call attention to specific areas during presentations or discussions.
• Presenters can collaborate without sharing their entire screen.
• The feature will be available by default once released to your tenant.
• Existing Teams meeting and sharing policies will continue to apply.
• No changes to admin configuration are required.

[What you can do to prepare:]

No action is required.

• Inform your helpdesk and training teams about this new collaboration capability.
• Update internal documentation related to Teams meeting or screen sharing workflows.
• Communicate this change to macOS users who frequently present content in Teams meetings.
