Last year, Microsoft seemed to be intent on pushing OneDrive as a serious competitor to the likes of Dropbox and Google Drive. It announced several promos, some of them permanent, to entice users to switch over to its cloud storage solution. Among them was a 15 GB starting space for all free accounts. Now it seems that Microsoft is rather abruptly and unceremoniously putting a stop to most of those benefits, ending the unlimited storage offer for Office 365 users and reducing the free storage from 15 to 5 GB. All because of abusers.
