Teams now supports live captions for meetings, but only for the English language. If you speak slowly and clearly into a high-quality microphone, you have a good chance that your words will be correctly interpreted. On the other hand, if you mumble or turn away from the microphone, be prepared for some interesting results. Overall, a nice enhancement that will be appreciated for those who need the captions.
The new Teams Calendar app gets a new feature called Meet Now to create on-demand or ad-hoc meetings that don’t need to be scheduled in anyone’s calendar. There doesn’t seem to be any reason not to allow users to use Meet Now, but if you need to block the feature, you can edit a Teams meeting policy and assign it to the unfortunate users.
