A method and system for reporting changes in personal information management (PIM) data. A user operating a client station subscribes to a presence server to be notified when a change in another user's PIM data occurs. The presence server responsively subscribes to a PIM host. When the designated change occurs, the PIM host notifies the presence server. The presence server then correlates the notification with the user's subscription and responsively notifies the user of the change.
