It could also be used by a family member in shared Apple services or iCloud features. Now that you know the causes, let’s discuss the solution.
1. Remove Your Secondary Email Address
Removing the secondary email from your Apple ID is important because it ends its link to your account. Apple’s system stops any linked email from being reused. By detaching it, the email can be used again for a new Apple ID or elsewhere without errors. The second option for removing an email address is from the Apple Server.
2. Try Another Email Address
Using a different email can solve the issue because it avoids problems with the current one. If your chosen email is linked to another Apple ID, a new or unused email prevents the “unavailable” error. This is a fast fix, especially if you need quick access, as it skips waiting for the old email to clear from Apple’s systems.
3. Try Another Email Provider
Using a different email provider like Gmail or Outlook can solve the problem if your current email is blocked by Apple’s system. This avoids conflicts with Apple’s rules on reusing emails. A new email from a provider not used with an Apple ID lets you start fresh without any issues.
