Currently we have over 9,000 users utilizing O365, with the license Microsoft Office 365 Plan A2 for Students. The Issue we are having is only select users when using Sky Drive Web Access are not able to use the Create Document button, it is greyed out. In problem solving the user was asked to try different computers and the problem still persisted. Also, other users were asked to login on the same machine, and they were able to use the create document button. I am unaware of a per user setting that would disable this feature.
