We have an hybrid setup and require to change the email field of more than 500 users to reflect something like below, need a script to do this.
Current domain new.edu.ik and email user@new.edu.ik but need that to be changed to new@alumni.new.edu.ik
Manually doing one by one is possible but need to do this task for bulk users,please advise a power shell method to add the new email and set that default and later to remove the old email.
