Abstract: An integrated system and method for implementing messaging, planning, and search functions in a mobile device. The system includes a messaging suite, a planner suite, a search suite, and a user interface configured to permit a user to interact with at least one of the messaging suite, the planner suite, and the search suite. An active resource directory is provided to store properties of objects associated with the messaging suite, the planner suite, the search suite, and to track one or more of the user's activities while accessing functions of the messenger suite, the planner suite, or the search suite. The system also includes a controller coupled to the messaging suite, planner suite, search suite, user interface, and active resources directory, where the controller is configured to provide integration of functions from each of the messaging suite, planner suite, search suite, and user interface.
