It was very surprising when Microsoft announced unlimited OneDrive storage for Office 365 subscribers back in October 2014 – Microsofts answer to Googles announcement to provide unlimited storage for educational users. Almost exactly one year later, Microsoft stated in a blog post that they are making changes to OneDrive storage plans.

How will these changes affect me?
Starting in early 2016 Office 365 Home, Personal and University subscribers will be cut to 1 TB OneDrive storage. If you are storing more than 1 TB in your OneDrive account, you will be notified to decrease your storage within the next 12 months. The 100 GB and 200 GB plans are no longer available to new users and will be replaced by a 50 GB plan. If you want to unsubscribe from Office 365 because of these changes, Microsoft offers a pro-rated refund.

But not only paid storage is affected. Also the free OneDrive storage is being down-scaled from 15 GB to 5 GB for all users. If you are using more than 5 GB space on OneDrive you will have one year to reduce the data below this limit. The 15 GB camera roll storage will be discontinued completely in early 2016. To see your plan and how much space you are using, visit the Manage Storage page.

What does it mean to OneDrive business customers?
Since the OneDrive storage plans changes were posted on the OneDrvie blog, there’s no statement about the impact to OneDrive business customers. This is a big question mark because Microsoft announced unlimited OneDrive storage for Office 365 subscribers one year ago – not only for Office 365 customers, but also for business customers.
While the OneDrive for Business service description (last updated on October 5, 2015) refers to a 1 TB storage limit, the Office 365 roadmap still shows «Unlimited storage for OneDrive for Business» as «in development», referring to the partly revoked blog post of October 2014.

This raises the question of whether the OneDrive storage limit for business customers will remain at 1 TB and no upgrade to unlimited storage will happen. We will see what the future holds.
