I had some fun getting to the bottom of this error and I found some potential issues that can cause this error to pop up that might not be apparent. We had the Azure AD user account configured for Azure AD Join and the user was not over the limit of devices they could enroll (default 5). What we did run into is two items that were generating the error.Don’t perform Azure AD Join with the default administrator account.Make sure the user performing Azure AD Join on the device is a local administrator.FYI: Also make sure the machine is not domain joined.Hope this helps your experience go a little more smoothly.
