Yes, this is possible. You can change your settings at any moment via the online customer portal. For example, changing the frequency of forwarding or changing your mailing address is easily done. If you change the primary processing setting (forwarding, scanning or storing), this will only take effect from the next billing period. However, the name of the applicant (Postbox holder) and possibly the company name (in the case of a business application) cannot be changed, because the agreement was entered into with this.
