Hi json-5198,
This is by design. As you said, if you want to limit the number of emails sent to users, it can be turned off.
If it cannot meet your requirements, we recommend you that please give a feedback to https://microsoftteams.uservoice.com/forums/555103-public/suggestions/41226928-audio-conferencing-license-removal-meeting-update.
Microsoft will always focus on customer’s feedback and experience. Some new features would be added to the services based on customers' feedback in the future, and your good ideas will be very helpful for them to improve the service.
Your time, understanding and cooperation will be highly appreciated.
