Кому то помогло это
This trick from Microsoft support fixed the issue for me:
If you are unable to create a Teams meeting from Outlook, please perform the below steps and let me know the outcome of it.
1. Quit all Office applications in your Mac device.
2. Open Microsoft Word.
3. Sign out of the account that is logged in.
4. Sign back in.
5. Now re-launch Outlook and try to create the meeting again.
