In such cases the need to convert the existing NSF file of configured Notes into PST format. Obviously, the reason is very clear that .nsf is the repository file type of Notes whereas .pst belongs to proprietary data files of Outlook. Hence, in such cases the Export Notes can be used without looking for any other alternative.
