Hello @Oleksii Melikov,
Thanks for reaching out!
I am not able to replicate the issue locally, can you please check if you are able to get the "joinUrl" for this online meeting in the response of the above API call?
You can also check if you are able to see the join button for the meeting from outlook calendar as in the below screenshot:
Also, please try to open the meeting from the teams and check if the join button is available.
Please validate the above and let me know if the issue still persists.
Hope this helps.
