I suggest using a professional and reliable tool to convert NSF file to PST instead of a manual technique. Since manual ways are not appropriate for novice users, thus a powerful tool like Lotus Notes to Outlook Converter can do the task well. The tool comes with an interactive interface for easy conversion. It converts Lotus Notes items like messages, contacts, tasks, calendars, etc. to PST without any difficulty. It can convert NSF to PST without lotus notes. It also allows users to convert multiple files or single files quickly.
