SET USERS AD HOME DIRECTORIES READ ONLY
Lets assume you are going to do a migration for users home drives to O365 One Drive for business. Par t of your migration you plan to lift user data to cloud then you need to configure users local network home directorates read only for some time. The idea is to make sure after data migration, users can no longer manipulate their local network home directories. Reason you want to frustrate them to move away using network drives and start using ODFB for day-to-day work load. The script I wrote is just going to do that. While user has read only access to their network drives, they can copy and paste anything they like to their desktop and once this is done they will have full NTFS access.
Use the script as you like and make sure it fits into your needs. You may need to adjust few lines and if you need help drop me a message, will be happy to assist.
