You can permanently delete your contacts in your address book.
To delete a contact, follow these steps:
Click the Groups tab on the left navigation bar.
Click the Group Memberships icon. The Active Memberships page appears.
Select the group in which you would like to delete a contact. The Group homepage appears.
Click the Shared Contacts button. The Shared Contacts page appears.
Click the contacts view button to view all your contacts on a single screen.
Locate the line of the contact you want to delete and click the delete link in the Modify column.
Doing this will delete your contact immediately.
Note: All
contact deletions are permanent and you do not have the opportunity to
retrieve a deleted contact. By default, pressing the delete link deletes
the item without any confirmation. To learn how to change the settings
of the delete button refer to the General
Preferences
topic in this help file.
