Microsoft offers 15GB of free storage for users of its OneDrive (formerly SkyDrive) product, which comes with most Office software or subscriptions. Users can store any file type in OneDrive but it is naturally well suited to Office documents, especially when it comes to real-time collaboration.
For further functionality and increased storage users can buy the Office 365 Home with Premium OneDrive Features package for £77 per year, or Office 365 Personal with Premium OneDrive Features for £54 per year.
Also, in February Microsoft made headlines when it launched an offer of completely free access to OneDrive for Business for the remaining term of any existing contract with rival cloud storage providers Box, Dropbox, or Google.
The offer was only valid until 30 June and limited to organisations that are not currently OneDrive for Business or Office 365 customers and who make a minimum 500-user commitment, but it does signal the importance of this market to the giant vendor.
