When trying to pull data from a SharePoint List Data Source, using the Microsoft Online Services ID, you may see the following output in your query:
DataFormat.Error: OData: The given URL neither points to an OData Service or a feed: ‘https://login.microsoftonline.com/login.srf?wa=wsignin1.0&rpsnv=2&ct=1375471406&rver=6.1.6203.0&wp=M....
You may also see an error saying “The user was not authorized”.
You may see one of these errors when you do not select “Keep me signed in” when logging into O365.
After putting the check in “Keep me signed in”, you should then see the proper output.
