Windows Address Book was a component of Microsoft Windows that let users keep a single list of contacts that could be shared by multiple programs. It was most commonly used by Outlook Express. It was introduced with Internet Explorer 3 in 1996 and improved upon in subsequent versions. The Windows Address Book API could query LDAP servers or read/write data to a local .wab file. Windows Address Book was replaced by Windows Contacts starting with Windows Vista.

Overview

Windows Address Book has a local database and user interface for finding and editing information about people, making it possible to query network directory servers using Lightweight Directory Access Protocol. Other applications can also use the program. Microsoft Outlook uses its own PST store for email messages. However, it can import contacts from the .wab format. Microsoft Exchange Server and Windows Messaging uses .pab files for Personal Address Book.

Features

Security risk

In May 2000, the ILOVEYOU virus showed how Windows Address Book could be part of an exploit to spread malware by accessing and sending emails to a user's contacts. This approach has since been adopted by many commercial spammers.
