We want to let you know about some upcoming changes to OneDrive. On August 10, 2016, the amount of storage that comes with OneDrive will change from 15 GB to 5 GB. We are also discontinuing the 15 GB camera roll bonus. You can learn more at our FAQ.

We realize these are big changes to a service you rely on. We want to apologize for any inconvenience they may cause you. We made a difficult decision, but it's one that will let us sustainably operate OneDrive into the future.
