If your service is canceled, you will be able to reactivate it within 30 days of the cancellation date. If you reactivate your account within these 30 days and your domain has not expired, you will regain access to your account, with a new billing date. However, any email messages previously stored in mailboxes associated with your account will not be recoverable, and your files may no longer be available.
