Changing Apple ID from Outlook to icloud
My icloud account was set up years ago before I had an iPhone with my Outlook email. Now I would like to create an icloud email account. I have viewed the articles on creating a new Apple ID and have gotten nowhere. I am currently signed in and went to system preferences and clicked on icloud. I get the query to choose my Apple ID and hit OK. It then confirms the address chosen and I click OK. After, it loops back to "You cannot change your icloud email address after creating it" and I get nowhere. Do I need to sign out on my Mac and iPhone first? I'm afraid of being locked out and want to get the sequence right.
