I know this is old, but just wanted to confirm it's still problem. Transcript from my chat today with G Suite Contact Us. They still owe me a call from a higher level support person. At the very least it would be nice for them to highlight the issues with using your business e-mail as a super admin and just provide a real super admin account for free. Even @Jordan above makes the case that it's best to turn off everything else.
Me: i am a super admin user as well as my partner, but we would prefer
a less omnipotent user as our personal accounts. do we need to create
a "non-person" account to act as the super user?
Google Support: Yes but in order for us to do that you need to assign
another super admin into your account
Me: so do i need to pay for an additional "non-personal" user that
acts as the super admin?
Google Support: is there another admin in your account?
Me: yes, but he doesn't need that access either.
Me: none of us wants automatic visibility into other calendars except
Google Support: that would be correct if no one of the current admins
wants to have admin access you need to create another user that can be
Me: it's an unfortunate structure. a simple on/off switch for the
super admin would solve the problem
Google Support: well someone has to be a super admin to have full
control of the Admin Console Allen
Me: i get that we need a super admin for the admin console, but the
Calendar is arguably not that
Me: it makes no sense
Google Support: let me check on this one Allen, but as a super admin
it is one of its privilege
Me: it should be analogous to e-mail
Google Support: for the email you won´t be able to sign in unless you
change the password
Me: as it should be -- their calendar should be similarly private and secure
Google Support: for the calendar you can view the events and not have
the right to change it
Me: that's not how it works - i can view and change anything on any calendar
Google Support: oh really let me double check on that
Me: my coworkers are listed under "My Calendars"
Google Support: We can resolve this through the Admin Console
Google Support: can you please login into your G Suite Admin Console?
and then click on Apps>G Suite> and then click on Calendar please
click on General settings
Google Support: and then there is a option in there that says Internal
sharing options for secondary calendars
Google Support: please select no sharing if you do not want to see
your users calendars
Me: Note on page: Users will be able to change this default setting.
Super Admins have 'Make changes and manage sharing' access to all
calendars on the domain.
Google Support: but to set your expectation, this setting might take
24 hours to propagate to all users
Me: it says the super admins still retain full access
Me: i don't expect this to fix my issue
Google Support: still checking on this one, Allen
Me: that's irrational... why are calendars an exception?
Google Support: because it is a privilege of an account admin Allen.
Me: I get it Tedd... it's a lazy design choice
Google Support: Well I do apologize for the design Allen
Me: there's nothing special about calendars that should allow this vs
how email is treated
Me: so we have reached a dead end?
Me: is there an escalation path? the only work around is an extra
$10/month for a super admin that is not a regular user account
Google Support: let me check Allen, please give me a moment
Google Support: what I am going to do is to hand you over to one of my
colleagues who can further assist you on this one, they are going to
get in touch with you within 24 hours
We'll see what they return with.
