Outlook To PST comparison Application

Program to be a .net windows forms application to access the local outlook profiles and open a PST file to compare mailbox items between the two services. Need ability to select items ( email, tasks, people, calendar) that are not found in either service in comparison and be able to copy them to the other. This is a outlook synchronization application but being able to select only certain items to be copied. Need to be able to sort by item type and by date and by folder. So a sync can be done at the folder level and by each item found that are missing from one or the other service . You can do the GUI that works similarly to a windows file explorer file sync or you can set up list tree views for each folder with check boxes for each item and folder. Need to be able to export all items that have been synchronized to a log file .
