As part of the update, Microsoft also added integrated capability for instant messaging with contacts on the Windows Live Messenger service. The feature was the realization of a project that began as "Windows Live Web Messenger" in 2007, a replacement for the outdated "MSN Web Messenger" service that was first introduced in August 2004. It was noted that the original "Windows Live Web Messenger" featured tabbed conversations in a "conversation workspace", however since its integration with Hotmail this has been removed.[35][36]
