Addresses created on the fly by a user are available to all users within the company.

3. From within the user profile, click the Records Management Access/Permissions link. The System Permissions screen opens.
4. Check the Create / edit shipping address user permission. 
5. Click Save. The user will now see the Add Address button on the Shipping Address List screen and will be able to create a shipping address on the fly while placing an order.   Users without this permission will not see this button.
