Troubleshoot device features in Microsoft Teams on the web

Applies To
Microsoft Teams

While using Teams in a browser, you might notice an app isn’t working with your camera, microphone, speaker, or location.

A common fix is to give the app you’re using in Teams and your browser permission to use these device features. 

This article applies to Microsoft Teams on the web (work or school accounts).

Important

Before you begin, save any changes in the app that you don't want to lose.

Allow the app to access your device features

  1. Do one of the following depending on where in Teams you’re using the app:

    1. When you're using the app in Teams: Select More options Microsoft Teams more options icon  and choose App permissions help shield .
    2. Use the toggle(s) to turn on device access.

  2. If Teams asks for access to a device, select App permissions help shield . In the dialog, toggle the relevant device feature settings on.
    toggle feature setting

  3. Close the dialog and refresh the app to apply the changes.

Allow the browser to access your device features

Give your browser permission to access your camera or other relevant device features the app wants to use. 

Check your browser settings: You may need to “allow” your camera and/or microphone to work in Teams.

Contact your IT admin: Some settings may be managed by your IT admin. Contact them for more details.
