The Cloud Office address book lets you manage your contacts and their information. You can create private and public address books and share them with other users.
You can also create your own distribution lists to send e-mails to several recipients in a group at the same time.
The global address book shows you all e-mail addresses within a Cloud Office group.
You can also synchronize the address book with your own device via CardDav.
You can also find more information about Cloud Office features in the online help.
