Version 3.1 of the CRM Data Explorer has been released. You can download the new version here:
This release is mainly to correct connection issues with Office 365 and CRM On Premise with ADFS.
If you had connection issues with the previous version, I would suggest you download the new version and retry the operation.
If you want more information on the CRM Data Explorer, visit the product page.
As always, thanks for you time and if you have any questions or comments, I'd love to hear them.
