Mark Kashman (@mkashman) is a senior product manager on the SharePoint
 marketing team.

Last week at the SharePoint Conference 2014 in Las Vegas, Jeff Teper made some exciting announcements regarding SharePoint Online limit increases.  I wanted to provide more details so you can digest what this means to you and your business.

We are making the following improvements to SharePoint Online:

  • A 1TB site collection limit for OneDrive for Business and team sites: allowing your teams to store more content in a single location.
  • Infinite tenant storage scale: bringing your content to the cloud without compromise.

These updates are rolling out live worldwide over the coming weeks. Let’s dive into the details.

1TB site collection limit increase for OneDrive for Business and team sites

Now you can spend more time sharing your personal work content. 1 TB will let you establish large team document centers that teams can use – and keep using over time – without needing to introduce unwarranted information architecture complexities.

All your site collections – private and public, managed from the SharePoint Online admin center – can now have up to 1TB of storage allocation. You simply assign the desired amount to the selected site collection. The same holds true for users’1 OneDrive for Business that start with a default of 25GB/user allocation. Your SharePoint Online admin can now allocate more storage, up to 1TB, to users in the following increments: 50GB, 100GB, 250GB, 500GB, and 1024GB.


The new storage quota increases limits for OneDrive for Business. Manage allocations in the SharePoint Online admin center.

Infinite tenant storage scale

SharePoint Online has seen explosive growth: a 485 percent growth in user access and a 500 percent YoY growth in customer content storage, since April 2013. In the simplest terms, this means customers are leveraging Office 365 more than ever before, both in their OneDrive for Business usage and in collaboration and portal sites.

Even with this impressive scale, for our largest customers there has been concern about scaling to meet their growing needs, particularly in the future, as data is growing at an increasing rate. So, Office 365 and SharePoint Online have architected the storage design to enable infinite storage scale – for current storage needs and unlimited future potential.

I’d like to take a moment to dissect what this means across storage of your Office 365 investment. Users get a default 25GB of OneDrive for Business storage, + 50GB of  email storage, + 5GB for each site mailbox you create, + your total available tenant storage, which for every Office 365 business customer starts at 10GB + 500MB  times the number of users1. If you and your company have growing storage needs across your various work streams and content types, we think you’ll find Office 365 offers ample headroom–on day one. And if you need more storage, you can now purchase unlimited additional storage right from within your SharePoint Online admin center at a cost per gigabyte (GB) per month.


You can click the Buy Storage button from within the SharePoint Online admin center to buy additional storage.

Frequently asked questions

Q:  Which Office 365 plans will get these SharePoint Online improvements?

A:  Office 365 Enterprise E1, E3, and E4 and Office 365 Education A2, A3, and A4 can have 1TB site collections and unlimited storage potential. The main caveats are that Office 365 Small Business comes with only one site collection, so the tenant storage maximum for it is 1TB. Similarly, those with Office 365 Midsize Business can use up to 20 site collections, so their storage maximum is 20TB.

Q. Does this announcement apply to Office 365 Home Premium subscribers?

A. No. This article does not apply to the Office 365 Home Premium offering, which combines the latest Office applications with Skype and OneDrive storage.

Q. Does this announcement apply to Office 365 dedicated subscribers?

A. No. The Office 365 dedicated plans are not receiving this same update, because they are managed in a unique, isolated infrastructure.

Q. Does this announcement apply to Office 365 government subscribers?

A. No. This article does not apply to Office 365 government G1, G3, and G4 offerings.

  1. Great news! Is there any change to the maximum number of site collections?

    • Regarding max number of site collections, it has not changed and we don’t have anything to disclose at this time. It is something we review often (our last increase went from 3,000 to 10,000). Appreciate your feedback if you have a proposal for what your particular requirement would be – please share here. And also, please work with your Microsoft account rep to further the discussion if it becomes at all a blocker.

      • Actually I see the max number of site collections being the major limitation in moving some of my customer solutions into cloud.
        We have many customers where a site collection is equal to the project site where collaboration with their customers takes place. This has both to do with security management and a legal boundary for content.

        One customer have more that 50000 site collections!

  2. Great! That deals with one of the difficult restrictions for our 8,000 users!

    Now we need the 5,000 entry limit on lists to be relaxed. With 8,000 users, doing anything with lists is really painful! Come on, is SQL Server really such a poor performer that this can’t be relaxed to 10k?

    Currently, we can’t even use the user list for our intranet portal because it exceeds 5,000 entries.

    • Please keep in mind that the 5,000 limit is a list “view” limit. And we do understand the feedback.

      A current solution is to utilize metadata-based navigation, and configure the most important columns as either key filters or hierarchies. That has the effect of making it really easy to create selective queries over large lists, and has built in fallback behavior for times when the user accidently selects too large a data set. The basics for setting that up can be found here:
      We have extensive documentation on designing large lists here –

      The breadth of SharePoint boundaries can be found here: — where it is documented that SharePoint lists support up to 30,000,000 items (or documents).

      Please review and let us know if this addresses your issue.

      • Our understanding is that it is more than a ‘view’ limit because any actions that impact the whole list are not available when the list/library contains more than 5000 items. This is a serious issue that I have not been able to find a solution for to date. We’ve been trying to split our lists to keep them under 5000 items which introduces other issues.

  3. “These updates are rolling out live worldwide over the coming weeks.”

    We are just about to rollout sharepoint and this is huge for us! Is there a specific date ? “Upcoming weeks” is kinda vague.

    • We don’t provide specific timing on a per farm basis. We progress without pause based on monitoring and success across the WW farms – and things are going well. Your phase of allocating X number of storage per your information architecture requirements should not be slowed – you can do this today – in prep for your future and ongoing usage of or migration of content. Glad you like it. You’re going to love SharePoint.

  4. Any idea when this will be available in the Office 365 Government cloud?

    • We don’t have specific timing for GCC, though can assert our intent is to also bring these scale improvements to the GCC farms.

  5. Great, when dealing with large onedrive storage, how does one best sync 1TB of data in onedrive for business?
