PowerShell: How to Stop Inheriting Permissions in SharePoint Lists

In this article, we’ll show you how to break permissions in SharePoint lists with the following requirements:

  • Allow the user to input the Site URL and List Name as needed
  • Break permission for the list if it contains permission inheritance
  • Remove all users from the list but retain the permissions of item Created By
  • Remove all groups from the list but retain Home Owners and Home Members group
  • Break permission for Items
  • Retain the permissions of item Created By
  • Add Owners group to all items

Allow the user to input the Site URL and List Name as needed

The script below allows the user to input the Site URL containing some special characters (e.g. %20 instead of space).

The script below allows the user to input the List Name required.
