Challenge
In the past I added some RSS feeds to outlook. For one of these feeds now I would like to know the original URL. But this is not very intuitive to eliminate.
Problem
Via (intuitive) right mouse click you could open a properties dialog of a feed.

But there is no hint for the URL!

Solution
You could find the information in the RSS Feed Options dialog
- Open Account Settings

- Double click the feed

- and voila - here is the URL
