Microsoft has announced it is ending support for its unlimited OneDrive cloud storage plan and will put a limit of 1TB on storage for Office 365 consumers.

Announcing the reason behind the move, Microsoft said that a small number of users misused the OneDrive cloud storage service since the company rolled out unlimited storage for Office 365 subscribers last year. It noted that some users backed up numerous PCs and stored entire movie collections and DVR recordings.

In some instances, this exceeded 75 TB per user or 14,000 times the average, the Microsoft's OneDrive Team said in a blog post late Monday.

"Instead of focusing on extreme backup scenarios, we want to remain focused on delivering high-value productivity and collaboration experiences that benefit the majority of OneDrive users," the blog post read.

As a result of the changes announced, Office 365 Home, Personal and University subscribers will no longer have access to unlimited storage. Instead, the current unlimited plan will now be capped at 1TB, reported CNET.

Microsoft's OneDrive will cancel the 100 GB and 200 GB plans for new users and will be replaced with a 50 GB plan for $1.99 a month, scheduled to be launched in early 2016.

Fre Microsoft OneDrive users will have their storage limit decreased from 15 GB to 5 GB and the 15 GB camera roll storage bonus will also being eliminated. These changes will roll out in early 2016.

Microsoft OneDrive team said it is offering a 12-month grace period for existing users to comply with the changes. After the grace period is over, the account will become read-only, with user access to the files for at least six months.

Individual OneDrive subscribers to the 100 GB and 200 GB plans will not be affected by the change, while Office 365 users will be eligible for a refund.

"If you are an Office 365 consumer subscriber and find that Office 365 no longer meets your needs, a pro-rated refund will be given," announced the Microsoft Ons Drive blog.
