If a site does not have an LDAP server to provide access to a corporateaddress list, the device will accept a Public Address Book file that contains a list of user names andassociated e-mail addresses. This file must be in a CSV (Comma Separated Values) format for thedevice to be able to read the file contents. The device can have access to both an LDAP server and apublic address book. If both are configured the user will be presented with the choice to use eitheraddress book to select e-mail recipients.The majority of word processing or spreadsheet packages will allow you to create a CSV file. A selectionof e-mail applications will also allow you to export a list of users in the CSV file format.
