Centrally adjust "Manage group email" settings

I have set up an O365 group primarily for use of the shared calendar and its utility on our office SharePoint site.  I have set members of this group who are allowed to submit events to the calendar.  Nobody in the group needs to receive invitations when an event is submitted.  I know that individually each user can adjust their settings for the group, but is there a way for me as group owner (and O365 admin) to centrally set "Don't receive any group messages" for all members of the group?  To be clear, "Send all group conversations and events to members' inboxes" is unchecked.  Desired O365 settings for all members of the groupThanks!

You can toggle the AlwaysSubscribeMembersToCalendarEvents and AutoSubscribeNewMembers (together with the SubscriptionEnabled one). But the last time I tried this, it didnt yet work as expected. And you cannot apply it retroactively.

Thanks Vasil!  I presume when you say that it didn't work as expected, you mean that you were unable to toggle the value at all...

PS U:\> Set-UnifiedGroup -Identity "GroupName" -AlwaysSubscribeMembersToCalendarEvents $false
A positional parameter cannot be found that accepts argument 'False'.

Am I missing something?

It's a switch parameter, the correct syntax is:

Set-UnifiedGroup -Identity "GroupName" -AlwaysSubscribeMembersToCalendarEvents:$false

Open in new window

It simply didnt seem to have any effect.
