Recently I had couple of customers asking me for a script where they can replace Everyone/Everyone except external users account in SPO with a different account/group.

Following script will copy permissions of an account to a new account.

  1. It will check for SharePoint Group membership

  2. It will check for SPWeb unique membership

  3. It will check for SPList unique membership

  4. It will check for SPFolder unique membership

  5. It will check for SPItem unique membership

After this script you can remove or even disable Everyone from showing in people picker.

 

Let me know your suggestions in comments. I will try to add your suggestions to my script.
