Hi Hidde,
The SkyDrive Pro URL is not correct. Please go to the Portal page, then click the 'SkyDrive' to the SkyDrive Pro page. After that, you will find the SkyDrive Pro URL from the browser. Here is one example: https://contoso-my.sharepoint.com/personal/andy_sek_contoso_onmicrosoft_com/Documents/Forms/All.aspx
I will wait for the information. Thanks for all your efforts.
Andy Sek
