You can easily join a Teams meeting anytime, from any device, whether or not you have a Teams account. Double check your appointment date and time and add a reminder to your calendar. If you don't have a Teams account, you can follow these steps to join. 

1.  Go to the meeting invite in your email inbox and select Join the meeting now.

2.  A web page will open with two options: Continue on this browser and Join on the Teams app. You don't need to install the Teams app to join the meeting. 

3.  Your browser may ask for permission to use your mic and camera. When you select Allow, you can always turn off your mic and/or video once you join the meeting. 

4.  When you're ready, select Join now.

Tip:  Join the meeting up to 15 minutes before the scheduled start time to test your setup, troubleshoot, or get familiar with how Teams meetings function. Meeting organizers and participants won't be notified that you've joined the meeting until 15 minutes before the scheduled start time. If you enter the meeting lobby, wait for the host to admit you. If you are ever removed from the lobby, you can try joining again.
