PowerShell: How to Delete Unique Permissions in SharePoint Lists

In this article, I’ll show you how to delete unique permissions in SharePoint lists with the following requirements:

  • Allow users to input Site URL and List Name as needed
  • Show the list of List Names on site
  • Ask users to select the numerical order of the list
  • Check to see if the list exists with Unique permissions or not
  • Reset broken list inheritance
  • Reset Items level inheritance

How does it work?

Download DeleteUniquePermission.ps1 file to your server.

Make sure that your site contains a list that has stopped permission inheritance for both List level and Items level.
