If you are looking for a simple way to
export Lotus Notes contacts to vCard I would suggest avoiding the long manual steps as they often create data mismatch issues. When I had to move my Lotus Notes address book I used the
Softaken Lotus Notes Contacts Converter and it worked really well. The tool directly converts Lotus Notes contacts into vCard format without losing any detail. It also allows exporting multiple contacts at once. You can export the NSF file contacts to multiple file formats with this tool like VCF, CSV, PST, and MSG.
