Taskline is an easy to use software addon for Microsoft Outlook that uses critical path techniques to reschedule Outlook's task list, assigning each task a recommended start and finish date. Scheduling takes into account your normal working week, and existing commitments in your calendar, such as holidays and meetings. Tasks can also be displayed in Outlook's diary, so that you can now have a single view that completely details everything you have to do, when, and in what order.
