Microsoft is making some changes to OneDrive (https://onedrive.live.com/about/en-us/), its file hosting service that allows users to sync files and later access them from a web browser or mobile device.
The amount of free storage that comes with OneDrive will change from 15 GB to 5 GB. Microsoft is also discontinuing the 15 GB camera roll bonus.
As a result of these changes, you will be over your OneDrive storage limit on Aug. 10. To bring your account within the new limits, you can purchase additional storage or choose to remove some files.
