Can I export my contacts to Outlook?

In iCloud Contacts, you can export to vcf by selecting contacts and choosing Export VCard from the menu under the gear icon in lower left. However, I've not had luck exporting more than a few vCards at a time. Maybe its just me or Maybe someone knows a work around. Give it a try yourself, but I would do batches instead of one export of hundreds. Double clicking the vcf should import to Outlook if you have that file association set up.

What's exported is dependent on what's selected when you choos to export. To expert all contacts you need to be at the All Contacts group.

Yeah, it is supposed to work that way, but when I select more than three, the export fails for me.... on two different Macs.

Don't select any of the actual contacts, just select the All Contacts group in the sidebar.

It went to the folder you have designated as your download folder. Usually it is named downloads.
