Address Book is where you can store contact details. By default a Contacts and an Emailed Contacts address book are created in Address Book. You can create additional address books and share them with others.
You can add contacts to any of your address books. Only a name is required to create a contact, or you can create detailed contact forms that include full name, multiple email addresses, work, home, and other addresses, phone numbers, and an image. You can also create group contact lists.
The Emailed Contacts address book is populated when you send an email to a new address that is not in one of your other address books. You can disable this feature from Preferences>Address Book.
Your email administrator can set a maximum limit for the number of entries you can have in all of your address books. When you reach this maximum, you cannot add any more contacts. However, you can delete unused contacts to free up space.
When you compose an email, the auto-complete feature displays a list of names from your address books that match the text you are typing.
You can share any of your address books. This is useful if your address books are for specific categories of contacts and want other users to have access to the names. Depending on the role you assign to the grantee, the shared contacts list can be view-only or can have full access privileges to edit, add, and delete names.
Other features include the ability to:
Apply tags to contacts
