I have some users that are unable to analyze in excel. They have downloaded the latest Excel updates from Power BI and also have OLE db providers for 2016, 2014, 2012 as well. As far as I can tell the OLE DB providers are all there and are the same as those on the computer where the user CAN analyze in excel. I cannot figure out the difference between their setups where one can analyze without issue and the other gets the error: The connection failed because user credentials are needed and Sign-In UI is not allowed. Is it something to do with Azure authentication?
