I am trying to set up an RSS feed using Microsoft Outlook from hackernews. Outlook is my mail client to check my office mails. (Email server using POP3.)
But when I say Subscribe now, it it opens Outlook on my Windows PC, but it gives an error as below.

What is the problem here? Do I need to change some setting in Outlook for this RSS feed?
How can I fix this to see Hackernews RSS feeds using my Outlook?
EDITED: Same error occurs when I try to subscribe to RSS feeds from reddit/r/programming.
