Do you want to resolve any errors in the Lotus Notes NSF file? I personally suggest installing the eSoftTools NSF to PST converter software in your computer or laptop. This software allows you to recover missing and crashed Lotus Notes NSF files without any errors. This tool always required Lotus Notes application because this tool can not convert NSF to Outlook PST and other formats without Lotus Notes application. But Outlook applications are not required for conversion and accessing PST files.
