In a company or a community environment, it is possible to give access to a common address book. This address book includes all contacts common to the enterprise or the community, avoiding the need for all users to have the same contacts in their personal address book. This also ensures that the contacts of the company are up to date. This address book is managed by an administrator of the company or the community. Other users have read only access to this address book. They can use the contacts of the common address book like those in their personal address book.
