It is imperative that all prerequisites are met, proper worfklow of how to invite MSFT teams meeting, as well as all the Account Settings listed under "How to Enable or Disable Third-Party Conferencing Dial-in for Zoom Rooms" of the article I provided.
If all the information in the article has been followed, but MSFT Direct Join is still not working, I would recommend submitting a Support Ticket for further investigation as it could be a parsing issue.
I have just tried to follow the steps, but at 3rd step, I'm not able to see the Account Settings tab. Please the attached image and advise, thanks.
1. Sign in to the Zoom web portal as an admin with the privilege to edit Zoom Rooms settings. 2. In the navigation menu, click Room Management then Zoom Rooms. 3. Use the Zoom Rooms location hierarchy to enable third-party conferencing dial-in for Zoom Rooms from the account, location, or room settings. For this example, click Account Settings.
The screenshot you provided indicates that you currently do not have a Zoom Room Set up for the account? Please make sure to log in to the admin account that was used to set up that Zoom Room. If we are needing to set up a Zoom Room, please use the documentation below for the initial configuration.
