Windows should recognise vcf files ok. How many vcf files do you have?
Outlook’s import function is limited to 1 vcf file at a time. The same is true for having multiple contacts in a single vCard; Outlook will only import the first contact in that file.
If you only have a handful of vcf-file to import, you could double click them to open them with Outlook and then press Save & Close to also actually save them in Outlook. This is of course quite cumbersome when you have lots of contacts to import.
To still be able to quickly import these contacts into Outlook, you can export to a csv-file instead.
To export to a csv-file, if you still have access to the original application holding your contacts on the Mac and it supports exporting to a csv-file as well, then this is the best approach.
Once you have your csv-file, you can import it via File-> Open & Export-> Import/Export-> Import from another program or file-> Comma Separates Values
Unfortunately that advice was incorrect - you cannot upload as a group to Outlook.
Do you still have access to the original application holding your contacts on the Mac? (e.g. Mac Mail)
Ok, where are your contacts stored on the Mac? Mac Mail, or something else?
Ok, the Contacts app only allows vcf or abbu format.
However there is another method you can use if the Mac has Numbers on it...
What version of Numbers do you have on the Mac?
Select all of your contacts in Contacts, press Command-c to copy them, then go to Numbers 3.5.2 and click once in a cell of an existing table, and press Command-v to paste. Then in Numbers, select File > Export to > CSV...
So now go to Outlook on the Windows computer and select Import and import the csv file.
comma separated file is csv
(comma separated value)
You can choose the Outlook Contacts folder, or any folder you wish.
Which version of Outlook are you using?
From the Help menu, click About Microsoft Office Outlook.
Before you clicked Finish to import all of the contacts contained within the CSV file to Outlook, did you map the custom fields first?
Ok in Outlook 2016 you'll need to go back and import again and map the custom fields.
To do that when importing, click on the Map Custom Fields… button, drag the values from the csv file on the left to the matching field on the right. You can check the map custom fields is correct for your contacts using Next and Previous.
Once you make sure all columns from the CSV file are mapped to the desired Outlook address book fields, click "OK" and finally click "Finish". Now, all of the contacts contained within the CSV file are successfully imported to Outlook.
