How to join a Microsoft Teams Meeting on desktop or web?
The Microsoft Teams desktop app and web application are identical when it comes to joining a meeting, so you can use the options below regardless of which platform you choose.
Join from Chat or Channel
You can join a meeting (even if it's already started) from the Teams “ Chat” section. If the meeting is taking place in a Channel , you have the option to join from there as well.
Click on “Chat” on the left side of the app and select the meeting. You will then see the “Join” option at the top.
If the meeting is in a Channel, simply select “Teams”, visit the channel and you will see the same option. Click “Join”.
Participation via Calendar
Another way to join a meeting in Microsoft Teams is from the “Calendar” section in Teams.
Click on “Calendar” on the left side. You will see the meeting on the correct date and time in the calendar. Select the meeting and click on “Join”.
Participation via link
In many cases, the person who organizes the meeting sends a link to the people who will attend. Through this link, you can easily join the online meeting at the appropriate time.
Click the link and the Microsoft Teams app will open on your device. If you have not installed the app, you will be directed to the web where you can join the meeting (only Edge and Chrome) or download the app.
