Additional calendar-related features and issues within Microsoft Teams for Education
Hi Clive,
Based on my research, the notification setting could only be managed by users themselves, it is not possible to change notification setting for all users in the company. If you really need to do that, I recommend you feedback it to our dedicated Microsoft Teams feedback forum, our development team is there and they pay high importance on customers’ feedback, many features have been updated after our customers post the demands there, thanks for your understanding and cooperation.
Kind Regards,
Betty
