Issue has now been resolved 12th January 2016
It has come to our attention that OneDrive is not loading correctly on curricular computers.
When a user tries to open OneDrive the top ribbon appears but the content is missing. We think that Chrome is trying to download a OneDrive plugin from the Chrome Store and that this download is being blocked.
IT are currently working on a fix for this but you can access OneDrive with Internet Explorer in the meantime.
