Microsoft Office LiveMeeting 2005 Web Parts

The Live Meeting 2005 Web Parts integrate Live Meeting with SharePoint (both Windows SharePoint Services and SharePoint Portal Server) to aggregate information together within a single portal so that teams can interact more effectively.

By integrating with Live Meeting Portal, users can seamlessly view their upcoming Live Meetings or recently made recordings without having to log-in or remember any passwords. Not only do the web parts provide a view into Live Meeting from SharePoint, but they also allow a user to conveniently publish meetings and recording into a shared event calendar, so that team members can interact more effectively by having everything in one place.
