set-msolgroup Calendar permissions

Fist of all, anything Calendar related needs to be handled with the Exchange PowerShell cmdlets, not the MSOL ones. Now, I assume the object in question is a "modern" Office 365 group, right? Just to confirm, run the following cmdlet (after connecting to ExO PowerShell):

Get-UnifiedGroup deuts*

Select allOpen in new window

Thanks,
I ran the command it shows Name, Alias, ServerName & AccessType

So it works.

Well, the bad news is that you cannot control the individual folder permissions for "modern" Office 365 Groups. Every user that's a member of the Group has the same level of permissions. The only possible thing you can do is to try the CalendarMemberReadOnly setting, which supposedly restricts the permissions on non-owners. However, I've never seen it working properly, so dont get your hopes high :)

Set-UnifiedGroup groupname -CalendarMemberReadOnly

Select allOpen in new window

What I want is that everyone in the company should have Read rights on the calendar, that is they can see the appointments... is that possible?
I have only 2 people who are member of this group, but I want that all users without joining the group should be able to read the calendar....
If not, what is the way out to make it happen?

Thanks!
