Verifying email address when adding a custom domain to email getting errors

HI, trying to use a custom domain name for my email, when I try to verify my families address, some get an error that they are "This email is already in use with another Apple ID". Some are verified. What could be causing this?

MacBook Pro 15″, macOS 10.15

If someone has already added this email address to their account, then the address with the same name cannot be added to another Apple ID. Even if that Apple ID has already been deleted.

Once you've added an email to your account, it's linked to it forever, even if you delete it.

Apple should explain this before letting people add mail or just fix this creepy bug.
