I do not have Teams installed on my device:
You can join a Teams meeting anytime, from any device, whether or not you have a Teams account.
Once you select the “Join Microsoft Teams Meeting” link a web page will load:
You can respond to menu selections or select “Continue on this browser” instead. Your browser may ask if it’s okay for Teams to use your mic and camera. Be sure to allow it so you’ll be seen and heard in your meeting.
Enter your name and choose your audio and video settings, and when you’re ready, hit “Join now”.
This will bring you into the meeting lobby. An ALEC meeting organizer will be notified that you’re there so they can then admit you.
If no one admits you to the meeting within 15 minutes, you’ll be removed from the lobby. If that happens, you can try joining again.
