Prefer only Export Notes Software to Convert NSF file to PST File. It gives you an option that after conversion you can save NSF files into both PST (97, 98, 2000, XP) ANSI & (2003, 2007, 2010) UNICODE. The limitation of 20GB of ANSI is resolved by this utility. Lotus Notes conversion is effective tool which can normally convert NSF Files into Outlook without any help.
