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. 


  • 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.

What'll work

Tons of great Teams calling and meeting features will still be available to you, including:

  • Powerpoint sharing

  • Whiteboard sketching

  • Meeting notes

  • Participant list

  • Meeting info

  • Recording

  • Live captions

What won't

Unfortunately, some important features won't be available. These include:

  • Video

  • Audio

  • Desktop, window, and app sharing

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, you'll need to use a phone for audio. Do one of the following:

Have Teams call you

Follow the prompts to have Teams give you a call.

Dial in manually

There are a couple of ways to dial in:

  • Use the phone number in the meeting invitation.

  • 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.
