Thank you for sharing such useful information. Sure one can try free NSF to PST converter software presented by eSoftTools. It can be used to export Lotus Notes emails to PST (MS Outlook). Other than NSF file conversion in PST file format, one can convert NSF file into several file formats consisting of HTML, EML, EMLX, MSG, MBOX and many other. The tool can be operated by the non-technical user without any doubt. All editions of IBM Lotus Notes and Windows can work fine with this tool. A trial version is present for free.
