Today I am considering using this PassFixer NSF to PST Converter tool which can easily make the conversion process of NSF file to PST and in 10+ more formats. Even that can display the entire preview version of NSF file items before the conversion such as emails, contact, calendar, etc. it has a user-friendly interface with simple and easy steps. Anyone can use this tool without installing window OS and MS Outlook. Read more from the official website of PassFixer.
