You can edit your Addresses by clicking on Menu in the top right of your Virtual Office homepage and selecting "My Account". From here all you need to do is click on "Edit Addresses" and edit the applicable fields for what information you need to update.

When saving the changes you will have a Pop-up asking if you want to update all existing subscription profiles to this subscription. Keep in mind if you select yes this will update ALL Shipping or Billing addresses on your subscription profile(s). If you select no the address will just be saved as the default for future order creation.

Each address update you save will be stored in the drop down above both your billing and shipping address respectively. These addresses can be deleted by selecting the address you wish to remove and clicking on the delete button below the address you would like to remove.
