The web browsers that Microsoft Teams supports are Google Chrome or Microsoft Edge. Prepare your computer to join Teams appointments You will NOT need to download the Microsoft Teams app unless you do not have a supported browser installed.
To join a meeting on a Windows Desktop, Laptop or a macOS device you can simply open the your Teams meeting link (most probably from your Outlook / Google Calendar) using your web browser. There are several ways to join, and you can use a variety of devices to connect. If you have received a Microsoft Teams meeting link from a customer or supplier but are not set up you with an Office 365 subscription nor do you have the Microsoft Teams app on your computer, good news, you can still join the meeting.
