OData error with Dynamics CRM Online
If you weren't prompted for a username/password it's possible you already had credentials stored. You could try deleting your credentials and connecting again, at which point you should be prompted to login and can choose Organizational Account. Sometimes that error ("neither OData service or feed") can be caused by connecting with the wrong credentails - the feed will redirect you to a login page instead of connecting to the feed.
I have also tried using the trailing '/', with no success. I am not using a browser to connect, but the actual desktop application.
