I’ve set up a custom domain for my email in my Apple account that I have shared with my family. I mistakenly set up one email address on my Apple ID intended for my wife. I promptly deleted it.
However, when attempting to set this email address on my wife’s account it says it’s in use with another Apple ID. A subreddit thread says you have to wait one year after deletion before being able to add the email address to another ID.
Can anyone confirm this?
