Thank you all for your comments.
Based on your feedback, we are updating the default privacy setting for groups created across all five Outlook endpoints (web, PC, iOS, Android, and Mac) to be private by default where only approved members can see what’s inside the group. For customers that want to continue with the existing behavior of public by default (where anyone in your organization can see what’s inside) we are providing an Exchange Online PowerShell cmdlet to define the default value. This update will gradually rollout to all Outlook endpoints in the coming months starting with Outlook on the web.
Keep your feedback coming.Jelle Vande Walle supported this idea ·Jelle Vande Walle commented
Same here. We are part of an educational facility.
1) Everybody can create groups ==> how can we forbid our students from creating public groups? The teachers should be able to create public groups. Without giving the admin rights, that is!
2) The option should be set to private as a default.
