from www.support.xerox.com this link should take you into how to work with your pub.ic address book.
no, you need to do it with the import export function on the webinterface of the machine
I need to add a new e-mail address and remove an old one from the public address book on our WorkCenter Pro 238 machine. Any guidance is appreciated, as I did not locate anything that helped under Xerox support. I thought this could be done directly from the WC machine.
Thank you.
