Address book for integrating email and instant messaging (IM)

摘要

Systems and methods for integrating instant messaging (IM) services and email services are described. In one embodiment, the email services and IM services are integrated through an address book database. The address book database correlates email information of a contact with a reference identifier (ID). Additionally, one or more IM addresses of the contact are also correlated to the reference ID, thereby permitting further correlation of a contact's IM information with the contact's email information.
