Hi Grundle,
In order to give more accurate information, I’d like to confirm the following information:
1. Whether are you using Skydrive or Skydrive Pro? If you are using Skydrive, do you have Skydrive Pro installed on your computer from Office 365?
2. Do you want to send mails via Outlook client or OWA (Outlook Web App)?
Regards,
Xinyu Zhou
