You can click on the purple Download the Windows / Mac app icon to download the Microsoft Teams desktop client, or you can click on the Join on the web instead icon. If you already have the Microsoft Teams desktop client installed, you can click on the Launch it now links below the two buttons.

Join via the Microsoft Teams desktop client

When you use the Microsoft Teams desktop client, you'll see Microsoft Teams pop up with a screen similar to the one above. From here, you can choose to immediately join the meeting as well as decide if your video should be enabled/disabled as well as your audio. By pressing the gear button beside the audio toggle, you can choose what speakers and mic Microsoft Teams should use.

You can also join the meeting without audio by clicking on the Audio off option. If the meeting supports it, you can also join by phone by clicking on the Phone audio option.

When you're ready to officially join the meeting, click the purple Join now button.

Join via the "Join on the web" option

When you join via the join on the web option, you may be prompted with a message similar to the one above. In your web browser, click on the Allow button to allow Microsoft Teams to use your microphone and/or camera.

Once permissions are granted, you'll be greeted with a screen similar to the one above. From here, you may be requested to type in your name for the meeting (if you're signed into Microsoft Teams in your web browser, you won't be asked this). You can also choose options similar to the desktop client, such as if your video should be enabled/disabled as well as your audio. By pressing the gear button beside the audio toggle, you can choose what speakers and mic Microsoft Teams should use.
