Microsoft Removes Storage Limits for Office 365 Users

Microsoft will begin offering unlimited OneDrive cloud storage at no additional cost to all Office 365 paid subscribers. The offer is being rolled out incrementally starting with Office 365 Home, Personal, and University customers.

In a blog posting, Microsoft's Chris Jones said that while the move to unlimited storage is an important milestone for cloud services,  he believes "the true value of cloud storage is only realized when it is tightly integrated with the tools people use to communicate, create, and collaborate, both personally and professionally."
