How do I enforce calendar permissions in Outlook on domain

I have just been asked to force permissions on user Outlook calendars i.e. so they do not remove them.  Is this a Group Policy solution, or Powershell?

Short answer is that you cannot.
A user owns their mailbox and therefore they control the permissions on the folders within.
Group Policy cannot do this for you, no idea why you were pointed to that. It isn't a setting controlled within the registry.

There are two solutions to this.

1. Create a script that will set the permissions for you in EMS, then set it to run regularly.
Anyone who removes the permission (or new staff) will get the permission set back. Those who keep removing the permission will soon give up when they see it comes back after a few hours or the next day.

2. Tell HR to do their job and make it a termination offence to remove the permission once set. Ultimately if the permission is being removed when users are told not to, then you are looking for a technical solution to a behavioural problem.
