If a user joins or creates an account joined to a team plan, they could add a personal email address to their account. Adding a personal email address to an account could allow the user to retain their account in the event their account is removed from the team plan.
Please note, adding additional email addresses to an account could be disabled by the team plan. Also, adding a personal email address to the account does not guarantee that an individual can retain their account and could be deleted by the team plan.
