I can add new email addresses to the address book on our WorkCentre 5890, delete addresses etc. Some email addresses can be added to the email favorites, but not those with a dot in the address. For example, firstl@example.com can be added fine, but first.last@example.com will not be added to the email favorites. I can click "email favorites" and then save, but the address will not be in the list of favorites.
Thank you in advance for your help!
That certainly isn't an issue on mine, so it must be a bug/glitch.
