Some browsers, including Internet Explorer, Firefox, and Safari, don’t support Teams calls and meetings.

While it’s best to download the Teams app or use a different browser, you can join a call or meeting on one of these browsers and use your phone for audio. You’ll just have some limitations. Here’s what you can expect.


  • If your meeting doesn’t have a dial-in number, you won’t be able to join it on the web. You need audio to participate in a meeting or call.

  • For more on supported browsers, check out Limits and specifications for Teams.

  • PowerPoint sharing

  • Whiteboard sketching

  • Meeting notes

What won't

Use your phone for meeting audio

If you join a meeting on a browser that doesn’t support calling or meetings and there’s a phone number in the meeting invite, then you’ll need to use a phone for audio. You can either have Teams call you or dial in manually.

  • Join the meeting online, then select More options More options button > Show call info and use the dial-in information or have Teams call you there

In the meeting details, you'll find dial-in numbers and an area you can enter your phone number and have Teams call you.
