When I'm exporting my contact list from outlook.com into csv file there's only one contact.

I click people tab, then manage and then "export for outlook and other services". The downloaded file contains only one contact as well as whole "people" tab. (same with the option: "export for outlook 2010 and 2013")

But I have hundreds emails in my inbox.

How do I extract all my email addresses into one file?

Please advice.
