Before a Meeting:
If the guest was invited to join the before the meeting started they will receive an email to join the teams meeting.
Once in the meeting users who are not part of the organization will “wait” in a virtual lobby and someone in the meeting will have to let them join.
Once they click “Open Microsoft Teams” they will be prompted to either open the teams desktop app if they have it installed or they can open the web app. From there they can navigate to their calendar on the right hand side of the screen to see their scheduled meeting
During a Meeting:
If the guest is added during a meeting the host will send them a link by email. The guest will receive an email with a link similar to the one on the right and once they click it they will be prompted to either join the meeting using the desktop app if they have it installed or to join using the web app
Important Notes:
If the guest user chooses to use the web app they won’t be required to download anything however it is important to note that the video and audio quality on the web app is significantly worse than the video and audio quality on the desktop app.
