Microsoft is overhauling its OneDrive storage options today, and taking aim at its big competitors. While a Microsoft account has always offered 7GB of OneDrive storage, that is more than doubling to 15GB this week, a figure that matches Google’s own free Drive storage. New and existing Outlook.com users will all benefit from the increased storage, but Microsoft is making even bigger storage tweaks for its Office 365 customers. All versions of Office 365, Microsoft’s subscription version of Office, will now come with 1TB of OneDrive space.
