I faced a similar situation some time ago. I wanted to import hundreds of contacts saved in VCF format into Microsoft Outlook 2019. I had to first search for free tools, but most of them lacked features or were not free at all.
Then I tried
WholeClear VCF to PST Converter. It is a simple tool that converts
VCF files to PST format, which can be imported into any version, including Outlook 2019. With this, you can convert one or more VCF files to PST at once. This tool keeps the data, such as names, emails, phone numbers, addresses, etc., completely safe and appears as it is in Outlook. There is no need to install MS Outlook for conversion and it supports Unicode PST files. There is also a free demo version available that lets you convert 25 contacts from VCF to PST. This allows you to experience its functionality first and then purchase a license as needed.
I found this tool extremely useful, especially when manually importing VCF files into Outlook was very time-consuming and gave limited results.
