In order to use Microsoft Teams effectively in the Meeting Room environment we recommend that enable "Anonymous Join"
Microsoft Teams is a new product and as such is under active development we make every effort to integrate with Teams Meetings as features become available.
In order to join a Teams Meeting as a guest without being prompted for credentials it is necessary to configure the Teams Server to allow "anonymous join"
Within the Teams Admin Center under Meetings - Meetings Settings you will need to enable Anonymous Join.
Joining via Web Browser
2019-May-05 At this time there are several constraints to using the Web Browser to launch a Teams Meeting.
1. Internet Explorer does not support Microsoft Teams
2. Chrome may prompt the user to download and install Teams from the Microsoft Store but will then load a web meeting.
3. Firefox only provides the ability to download the Teams Windows Application.
4. Edge - Microsoft will not allow you to directly join the meeting via the web interface. You will be first prompted to download their Windows Application each time.
