You can grant access to your contacts to other users. The user may then subscribe to your contacts. The access permissions range from being able to read your contacts, to allowing another user to create, modify, or delete contacts.
Right-click Contacts from Folders — your user name and select Properties.
The Contacts Properties window appears.
Select the Permissions tab.
Enter the user's ID and click Add, or click Search to search for users in your Address Book directory.
Choose the permission settings when the user's ID is highlighted.
Click OK to delegate access to your contacts to the specified user.
