I think you should try TrustVare NSF Contact Converter I used it recently to move all my Lotus Notes contacts. It works flawlessly as both an NSF to vCard Converter and an NSF to VCF Converter. I managed to convert NSF to VCF without any loss of data or structure. The process is effortless and does not need any technical experience. It's compatible with all versions of Windows and commonly used vCard versions such as 2.0, 3.1, and 4.1. You can even test the free demo before buying it.
