I also struggled with this. Outlook’s manual method often misses fields like phone numbers, email IDs, or images because it doesn’t handle vCard formats properly. The only way I solved this was by trying 
WholeClear VCF to PST Converter. It’s designed to preserve every property while moving contacts. I was able to 
convert VCF to PST with full accuracy, including contact pictures and job titles. The tool worked much better than manual steps, especially when handling contacts from different sources like Gmail and iCloud.
