Under the deal, HP will participate in AOL's Enterprise AIM Certified Partner programme, allowing it to build applications using AOL's corporate instant messaging products, including an enterprise gateway and a private domain service with authentication, in addition to the IM software.
AOL boasts one of the leading consumer IM services with more than 195 million registered users who send more than 1.5 billion instant messages per day.
Its recent move into the corporate IM market is meant to drum up revenue for the Internet division of AOL Time Warner, which has come under increased pressure to make ends meet in a weak online ad market and slower subscriber growth.
Rivals including Yahoo! and Microsoft have also moved into the corporate realm, which has been adopting the collaboration tool at a fast rate.
