Camera Not Working on Microsoft Teams? Fix the Black Screen

Last reviewed · fixmic team

Teams shows your meeting is connected but your video tile is black, or the camera doesn't even appear in the device list. Steps assume New Teams (the 2024+ rewrite, an MSIX/UWP app on Windows); Classic Teams retired in July 2024. Four things cause nearly every case: the wrong camera selected, a missing OS-level permission, another app already holding the camera, or a stale Teams device cache.

Check the camera dropdown before anything else

In a meeting, click the arrow (^) next to the camera icon on the toolbar → 'Select a Camera', or open Settings → Devices → Camera. Cycle through the listed cameras — laptops sometimes default to a disconnected external webcam or a virtual camera installed by other software. The moment the preview shows you, you're done.

1. Select the correct camera in Teams' device settings

Teams remembers a camera choice that may no longer be the one you want, especially after connecting or disconnecting an external webcam.

  1. Settings → Devices → Camera

    Click your profile picture → Settings → Devices. A live preview sits above the 'Camera' dropdown — cycle through the listed entries until the preview shows you.

  2. In a meeting: arrow next to the camera icon → Select a Camera

    Mid-call, click the small ^ arrow beside the camera button on the toolbar and choose the right device from the list — no need to open full settings.

  3. The pre-join screen has its own picker

    Before you join a meeting, the 'Choose your video and audio options' screen has a separate camera picker from the in-meeting one. Check it here too if the preview is black before you've even joined.

2. Grant Teams camera permission

New Teams runs as an MSIX/UWP package on Windows and a regular app on macOS. Each OS has its own permission gate that's separate from Teams' own settings.

  1. Windows: Settings → Privacy & security → Camera

    Confirm 'Camera access' and 'Let apps access your camera' are both on. New Teams is listed as 'Microsoft Teams (work or school)' — enable it. The legacy 'Microsoft Teams' entry refers to Classic Teams (now retired).

  2. macOS: System Settings → Privacy & Security → Camera

    Enable Microsoft Teams. macOS requires you to fully quit Teams (Cmd + Q) and reopen it for the change to apply — closing the window is not enough.

  3. Browser Teams (teams.microsoft.com)

    Click the site-information icon on the left of the address bar → Camera → Allow → reload the tab.

3. Free a camera another app is holding

Most webcams can only feed one app at a time. If Zoom, the Camera app, OBS, or a browser tab already opened the camera, Teams gets a black frame instead of your video.

  1. Quit every other video app

    Close Zoom, Google Meet tabs, the Camera app, OBS, and FaceTime. Check the system tray / menu bar for apps still running in the background, then restart Teams.

  2. Check the physical privacy shutter

    Many laptops and external webcams have a sliding cover or a camera-off keyboard key (often F8/F10 with a camera icon). A covered lens looks exactly like a software black screen.

  3. Reseat an external webcam

    Quit Teams, unplug the webcam, plug it into a different USB port (ideally a blue USB 3.0 port directly on the computer, not a hub), then reopen Teams and re-select it in device settings.

4. Check for an organization camera policy (work/school accounts)

On a managed work or school account, IT admins can disable camera access at the tenant level through Teams admin policies — this looks exactly like a broken camera, but no local fix solves it.

  1. Look at whether the camera toggle itself is unavailable

    A policy block usually makes the camera button greyed out and unclickable, rather than clickable with a black preview. That distinction points at IT policy, not a device problem.

  2. Ask your IT admin about the meeting policy for your account

    Admins control this under the Teams admin center's meeting policies. Ask specifically whether camera/video has been disabled for your account or your organization's default policy.

  3. Personal accounts are unaffected

    This only applies to organizational (work or school) accounts. A personal Microsoft account signed into Teams doesn't have this restriction available to an admin.

5. Clear the Teams cache

Teams caches device IDs and settings. After hardware changes or an update, the cache can get out of sync — the cached camera 'exists' in Teams' memory but no longer produces a working feed.

  1. Quit Teams completely

    Right-click the Teams icon in the system tray (Windows) or menu bar (macOS) → Quit. Confirm in Task Manager / Activity Monitor that no Teams process is running.

  2. Windows — easiest path

    Settings → Apps → Installed apps → Microsoft Teams → Advanced options → Reset. This clears the cache without manual file deletion.

  3. Manual cache delete

    Windows: delete %userprofile%\AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams. macOS: delete ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams and ~/Library/Containers/com.microsoft.teams2, then reopen Teams and sign in again.

Teams camera still black?

If the right camera is selected, permission is granted, no other app is using it, admin policy isn't the cause, and the cache is cleared:

  • Open your computer's built-in Camera app (or Photo Booth on Mac). If it's black there too, the problem is the OS or hardware, not Teams — see the Windows or Mac camera guide.
  • Reboot once. A camera held by a crashed background process is released on restart.
  • Update Teams — Profile picture → 'Check for Updates'. Many camera bugs are fixed in point releases.
  • On a managed/work laptop, a VDI or virtual-desktop setup can block direct camera passthrough into Teams; ask IT whether camera passthrough is enabled.
  • Update your webcam and GPU drivers — an outdated graphics driver is a frequent cause of a detected-but-black feed.

Confirm your camera works

Run the live camera test before your next Teams meeting. It shows your webcam feed in the browser in one click — so you know the camera itself is fine and the issue is just Teams' settings.
