Create an extra mailbox for your children, partner or yourself ((e.g. to have more storage space for your e-mails). The number of free mailboxes you can have depends on your Internet subscription.
You will receive a confirmation e-mail at the e-mail address you have chosen. Use the login and password you find in this e-mail to log in.
It is not possible to delete a mailbox. But you can delete or change the e-mail addresses linked to a mailbox. .
