SharePoint Online now allows up to 1TB of storage for OneDrive for Business and SharePoint site collections in Office 365

NOTE: Update 4-30-14 - This has all changed as we now provide 1TB of default OneDrive for Business quota per user. Please see new  my new blog post here and ignore the old scenario below.

Great news you can now up your SharePoint OneDrive for Business quota to 1 terabyte up from the default 25GB and previous upper limit of 100GB.


The way it works is you can specify which specific users you want to assign new upper quotas of 50GB, 100GB, 250GB, 500GB or 1TB quota. The catch to this is once you exceed the default quota of 25GB for a user you will be pulling storage out of your overall pooled tenant storage allocation (10GB + 500MB x total number of users) in your tenant.

For example:

If you have 10,000 A2 licensed users that equals 5TB of pooled tenant storage available.

You decide to up OneDrive for Business quota from default 25GB to 250GB for 4 users which consumes 1TB out of the 5TB leaving 4TB remaining of the overall pooled storage.

You can purchase more pooled tenant storage at a per GB / per Month charge if you require more.

The SharePoint site collection limit has also been upped from 100GB to 1TB max and the 25TB max SharePoint Online limit in a single tenant has been removed which means you can purchase as much pooled storage as needed in your tenant.

You can read more on how to configure OneDrive for Business and site collection quotas here and here.

    The official blog post at says that it will be Truly 1 TB per user… your post mentions otherwise… could you confirm if 1 TB is indeed the storage each user will get and the actual pooled storage will not be impacted?

    You can also create new document libraries in the personal site (MySite) apart from the OneDrive library.

    Yes, this post came out prior to this announcement a few days ago. We originally uppped the quota limits to 1TB but left the default quota at 25GB per user in this post. I will add a Note to reflect that recent change. Please see my new blog post here regarding the new announcement here:

    Current Sync limits are 20,000 files per document library in OneDrive for Business. You can have many document libraries via subsites in OneDrive if needed: Documented here:

    @Badajoz, there are SYNC limits not file limits. You can have many files well above 20,000 in your OneDrive for Business just cannot sync it all down locally. @Jen – it is available now for Enterprise/Commercial Office 365 tenants

  6. stephen says:

    Can you increase the number of files that can be saved in each site collection?

  7. Jen says:

    When will this get pushed to Enterprise/Commercial customers??

  8. badajoz says:

    The 20,000 limit is a really hard thing to sell to business

  9. Keith K says:

    @markga – this post/ update also references an increase to file size allowed, please confirm this is correct.
