U2U Caml Query Builder NullReferenceException Connection Error

Question

Our tenant is hosted by SharePoint Online SPO via .sharepoint.com and our domain uses Active Directory Federation Services for authentication within and multifactor authentication when outside the domain. I'm receiving a NullReferenceException error when connecting to SPO within the domain. Our TEST tenant does not use AD FS and I can connect U2U to TEST with no issues. Below is the message from the error dialog box.

What must I do to connect through AD FS with this tool?

System.NullReferenceException: Object reference not set to an instance of an object.

Thanks for your review!!!

Hi @Rob Hills ,

Thank you for the detailed case description. When I received the case, I searched a lot of documents did a lot of researches and test. And I feel regretful to inform you that U2U Caml Query Builder cannot connect to a SharePoint Online account with multi-factor authentication.
