Updated April 23, 2025:2026: We have updated the timeline below.and content. Thank you for your patience.

Coming soon for Microsoft Teams: Meeting participants will be able to request an annotation session while someone else is sharing their screen.

This message applies toApplies to: Teams for Windows desktop and Teams for Mac desktop. (Usersdesktop 

Introduction:

All meeting participants joining from native apps on Windows and macOS will be able to request to start collaborative annotations when a screen or window is being shared. The annotations start only after the active sharer approves the request. This capability is available exclusively in the new Microsoft Teams experience on native Windows and macOS apps.

This release also introduces a meeting option in the Participation section, allowing organizers and co-organizers to choose who can start annotations. By default, "Everyone" can access the "Start Annotation" button, but organizers and co-organizers can limit it to just the "Active Sharer", making the button visible only to the person currently sharing their screen or window.

Note: Users can view and annotate in Teams on the web but cannot initiate annotations.) Anonymous users in the meeting will not be able to send a request.

This message is associated with Microsoft 365 Roadmap ID 89975.

When this will happen:

Targeted Release: We will begin rolling out early June 2025May 2026 (previously mid-April) and expect to complete by mid-June 2025.May 2026 (previously late April).

General Availability (WW, GCC, GCC High, and DoD): We will begin rolling out mid-June 2025May 2026 (previously late March) and expect to complete by late June 2025.May 2026 (previously late April).

How this will affect your organization:

After the rollout, meeting participants who are not sharing their screens will have the ability to request an annotation session. This request will be sent to the presenter sharing their screenscreen, who can choose to accept or deny it: it.

Meeting Organizer Settings (Meeting Options)

IfA new "Who can start annotations?" option appears under the Participation section in Meeting Options. Organizers and co-organizers can select:

• Everyone (default) — All participants see the "Start Annotation" button
• Active Sharer — Only the person currently sharing sees the annotation button

After rollout, the default value of Everyone will apply to all newly created meetings. For meetings created before rollout, the setting will be Active Sharer to match the current behavior where only the active sharer can start annotations. Organizers and co-organizers must manually update existing meetings if they want to enable the new behavior for those meetings. 

Participant Annotation Request Flow 

When a participant who is not the active sharer wants to annotate, they click the "Start annotation" button in the meeting toolbar. A confirmation dialog appears, and once the participant clicks "Request", a notification is sent to the presenter for approval.

1. Click the "Start annotation" button in the meeting toolbar to initiate an annotation request.



2. Confirm the request in the dialog box. Once approved, annotations start request will be sent to active sharer



3. Request sent notification confirms the request is accepted,pending and the annotation session willpresenter needs to approve it. 

Presenter Approval Experience

The active sharer (presenter) receives a notification at the top of their screen indicating that a viewer wants to start for everyone in annotations. The presenter can choose to Deny or Allow the meeting: request.

Anonymous users in the meeting will not be able to send a request.

This change will be available by default.
