I faced the same problem after switching to Outlook and my phone. The best method I found was using TrustVare NSF Contacts Manager. It allows you to convert NSF to VCF in a few clicks. The exported file works perfectly with Android, iPhone, and Outlook. I liked that this NSF to vCard Converter preserves all contact details and supports batch conversion too. You don’t have to be technical—it’s very user-friendly. The NSF to VCF Converter feature ensures complete accuracy. I used the demo first to test it and it worked so well that I bought the full version.
