We have a need to create a Group in O365 where all current and new members have the Follow in Inbox feature "Only Replies to You"
I'm unable to find any documentation relating to this.
The Set-UnifiedGroup Command allows us to autosubscribe new members but then they get all messages in the group and there is a requirement that they only get replies directed to themselves.
I can see the options to do this on a user by user basis in Outlook Desktop and Web but users are not following the instructions.

There's no PowerShell cmdlet for this, best you can do is add to the "subscribers" list, either on the group level (Set-UnifiedGroup) or per user (Add-UnifiedGroupLinks). Neither gives you the granular controls we have in Outlook/OWA.
