Address Lists are part of Exchange functionality not Active Directory which is what I think people are confused about.

Anyway, Address List data is stored in the Active Directory Configuration context under:

CN=Address Lists Container,CN=<EXCHANGE ORGANIZATION NAME>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<DEFAULT NAMING CONTEXT>

You can use ADSIEdit to view the information.

In C# you can use an LDAP query to retrieve information for existing Address Lists.

Edit: Something like this:

DirectoryEntry rootDSE = new DirectoryEntry("LDAP://RootDSE");
DirectoryEntry configContainer = new DirectoryEntry("LDAP://" + rootDSE.Properties["configurationNamingContext"].Value);
DirectorySearcher configSearcher = new DirectorySearcher(configContainer);
configSearcher.Filter = "(&(objectClass=addressBookContainer))";
configSearcher.PropertiesToLoad.Add("displayName");
configSearcher.PageSize = 10000;
configSearcher.SearchScope = SearchScope.Subtree;
SearchResultCollection results = configSearcher.FindAll();
