Microsoft has removed the unlimited storage tier from its OneDrive subscription plans, and cut down the free storage tier from 15GB to 5GB. The company says a percentage of its users were abusing the unlimited storage tier, backing up multiple computers and storing their entire movie collections and DVR archives. At least one user managed to upload 75TB of files to the service. Microsoft says that it wants OneDrive to be a tool for productivity and collaboration, not a backup service.
As a result, all Office 365 Home, Personal, or University subscriptions will have a 1TB cap. The 100GB and 200GB plans will be nixed in "early 2016," and they'll be replaced by a 50GB plan at $2 per month. That's also the date when the OneDrive free plan will have its storage cut from 15GB to 5GB, and the 15GB camera roll bonus removed.
Microsoft will notify Office 365 users affected by the 1TB change, and the company will allow excessive users a grace period of 12 months to get their files off the service. Users subscribing to the free tier also get a year-long grace period to adjust to the 5GB space and a free one-year subscription to Office 365 Personal, which includes 1TB of storage. Current subscribers to the 100GB and 200GB plans remain unaffected. Finally, if you're displeased with these changes, Microsoft will give you a prorated refund of your Office 365 subscription.
