I'm trying to recover a Microsoft Outlook data file. Your tool initially finds 40,456 objects, but the recovered pst file contains 40,337 objects according to the program report. What happened to the missing 119 objects?
Answer:

Microsoft Outlook data files contain main objects (messages, contacts, notes, reminders, attached files and others) and service objects that are not shown to the user. While writing the recovered data to the new pst file, the program does not write some service objects because there is no need to do it.
