Microsoft is currently working on increasing the file size limit upload on its OneDrive from 2GB to an unspecified amount. A Microsoft spokesperson told The Next Web that they are currently working to increase the file size limit for all OneDrive users. They currently rolled it out to a small number of customers and will make it available to everyone in the near future. They did not give a specific timeframe when it will be available but they will announce it on their blog when they have done so.
