Allow Group Admins to enable/disable a private group from receiving mail from non-group members in the tenant
Currently, anyone in the same tenant as a private group can send unsolicited email to that private group, even if they are not a member of the private group. It would be a great improvement to O365 Groups if group admins could enable/disable their private groups from receiving email from non-group members. A similar option already exists for allowing/preventing folks external to the tenant from being able to email a group, public or private.
Admin can leverage this option “-AcceptMessagesOnlyFromSendersOrMembers” from the Set-UnifiedGroup cmdlets: https://technet.microsoft.com/library/mt238274(v=exchg.160).aspx

In my mind this doesn't solve the problem. The Group Admin, not the tenant admin, should be able to make this change via the group settings GUI. We have an extremely large tenant and if end users can create the group and be admins of that group then they should have that control. Our tenant admins do not have time to manage this via powers he'll.

Great to hear--thank you for the update!
Our customers would love to be able to make a group in our tenant truly private.
