I am trying out the Create Exchange Item activity for the first time. I reached the point where you setup a connection to the server. There is a field for URL but not specification of which URL (there are many web services hosted on an exchange server)

In the documentation it just says to select type exchange and everything else is optional. So the URL is not required? How do you specify the server address so it knows how to contact it.

I was looking for some more information on what this URL might be. Trying random Exchange URLs is leading to errors and I want to get it filled out correctly.
