Share Whiteboard from content from camera is broken

I encountered the exact same issue with Teams content sharing in both the Windows and Mac apps. Edge detection works correctly in the preview window, but once sharing starts, the shared feed reverts to the original camera view.

Hi SURASIT PHOONSAWAT,

I’m sorry to hear you’re having an issue sharing the Whiteboard using the Camera in Microsoft Teams. Below are some suggestions that may help improve the issue:

Check if Microsoft Teams is updated

Open Microsoft Teams.

Click your profile picture in the top-right corner.

Select Check for updates.

Restart Teams after the update completes.

Check camera permissions in Windows

If Teams cannot fully access the camera, the auto frame detection and pen overlay may not work properly so please check:

Open Windows Settings.

Go to Privacy & Security.

Select Camera.

Ensure the following options are enabled:

-Camera access = On

-Let desktop apps access your camera = On

-Microsoft Teams = Allowed

Improve whiteboard auto-detection

The Whiteboard camera feature relies on AI detection. If the whiteboard is not detected correctly, the overlay tools may not appear. Please try the following adjustments:

Ensure the entire whiteboard is visible in the camera view.

Increase room lighting if possible.

Avoid strong reflections or glare on the board.

Move the camera slightly farther away from the whiteboard.

Keep the whiteboard rectangular and center within the camera frame.

Test with another camera

If you are using an external webcam, you may try:

Switching to another camera in Teams > Settings > Devices.

Updating the webcam driver.

Reconnecting the USB webcam.

Clear the Teams cache

If the issue occurs in the Teams desktop client, clearing the cache may help. You can follow the instructions in this official article: https://dori-uw-1.kuma-moon.com/en-us/troubleshoot/microsoftteams/teams-administration/clear-teams-cache

Repair the Teams application

Open Settings from the Start menu.

Go to Apps > Installed apps.

Locate Microsoft Teams.

Click it and select Advanced options or Modify (if available).

Choose Repair and follow the on-screen instructions.

If the issue persists, repeat the process and choose Reset or Uninstall, then reinstall the application.

I hope the information above is helpful. If you have any further questions, please feel free to reach out.

The Whiteboard option under Content from camera should still provide framing and optimization for a nearby whiteboard, but it depends on the Teams desktop app and the camera correctly detecting the board.

Based on the documented behavior, verify the following end-to-end to rule out configuration or usage issues:

1. Use the Teams desktop app on Windows or Mac (not mobile or web).
2. In a meeting, select Share → Content from camera → Whiteboard.
3. Position the camera 3–4 feet away and centered on the whiteboard so Teams can detect its edges. If the board is not detected, the optimization (framing and transparency overlay) will not be applied.
4. Ensure the room is well lit and that dark-colored markers are used; this improves detection and clarity.
5. Confirm the correct camera is selected in Teams and that it is not already in use by another app.

If these steps are followed and the whiteboard is still shown only as a raw camera feed (no framing/overlay), this indicates a regression or service issue rather than a configuration problem. In that case:

• Test with Content from camera → Document to confirm that camera-based optimization works at all.
• Test from another device and/or account to see if the behavior is tenant-wide.
• Collect screenshots and meeting details and open a support ticket with Microsoft 365 support so the issue can be escalated as a potential regression in the Whiteboard camera feature.
