The corporate address book contains the contact information of the members and groups of your organization. The corporate address book contact information is taken from the directory server and cannot be modified in Convergence. In the Convergence UI, the corporate address book is called the Corporate Directory.
When working with the corporate address book, you can do the following:
How Do I Send an Email to One or More Contacts From the Corporate Directory?
How Do I Schedule an Event With One or More Contact In the Corporate Directory?
