We just realized Microsoft OneDrive is launching, also, we got their official email notify about the launching event.:
You’re the first to know
We wanted to tell you the minute we began rolling out OneDrive. It’ll start showing up online at OneDrive.com and in app stores in the coming hours. We couldn’t be more excited about the launch and hope you are too!
But the strange is that url is still preview.onedrive.com.
Also, please check OneDrive official blog about new OneDrive launching:
