If your groupware server supports multiple address books and you have access to the NotifyLink Client Web you can select the address book you wish to synchronize to the device.
Note: The device will synchronize only one address book, but you may choose which one it syncs.
From the NotifyLink Client Web home page,
Select PIM > Contacts > Choose Address Books and check the address book to be monitored.
Note: FirstClass, MDaemon, Meeting Maker, Mirapoint, oracle, and Sun Java Enterprise System collaboration suites do not support multiple address books.
