If you have shared an e-mail address with another person, this can only be used for a personal account in future. If you have any questions about this, please contact kundenservice@springermedizin.de.
Note: If you would like to change the email address you have registered with us on the My Profile page, this is only possible if you still have access to the email inbox that matches the email address currently in use (because a confirmation link will be sent to the old address by email). If you no longer have access, please contact kundenservice@springermedizin.de.
