Previously, users received 7GB storage space for free, but the increase to 15GB makes it comparable to one of OneDrive’s closest rivals, Google Drive. Microsoft also reduced the monthly price of 100GB to $1.99, down from $7.49, while 200GB costs $3.99.
Meanwhile, Office 365 users will get 1TB of free space, up from 20GB. That amount of storage space was originally reserved for Office 365's business users only. If you’re an existing OneDrive or Office 365 user you will automatically receive these new storage caps.
All of these changes will take effect next month. You can find out more about the storage limits and new prices on the OneDrive blog.
