@Thomas ,
Could you provide us a screenshot of the error message if possible?
Does this issue exist all the time or just appear in the new version?
Does anyone else have the same issue?
I tested in my lab. The result is the same when I use Microsoft Teams - Insiders.
Currently, only Microsoft Teams – Insiders have version 1.4.00.4855. When you open teams meeting link in browser, it will open Microsoft Teams-Preview, not Microsoft Teams - insiders. If you only install Microsoft Teams - insiders, it cannot join a meeting in Teams client by meeting link from browser.
The workaround is to send the meeting link in conversation. Then open the meeting link in the chat window as below:
Another workaround is to join the meeting from calendar as below:
We will work on this problem. If there is any update, I will share with you here.
