To transfer multiple VCF files to your Outlook PST, I recommend you use the DailySoft VCF to PST Converter program. It can convert one or more VCF contacts to PST files in a single process. The application is safe and maintains folder organization and data integrity when exporting files. You do not need the Outlook application when using the tool. It works with all Windows versions, including 11, 10, 8.1, 8, Vista, and XP. You can test the program's features in more detail by downloading the free trial version.
