1 Learn how to find the total and available storage for your organization. You can purchase an unlimited amount of additional SharePoint storage. See Change storage space for your subscription.
2 We recommend monitoring the Recycle Bin and emptying it regularly. The storage space it uses is part of the organization's total storage limit.
3 If you have an Office 365 subscription and an Office 365 Extra File Storage add-on, the storage amounts are added.
4 This is the storage limit for a single site collection, not the amount of storage provided for each site collection. This limit applies to all types of site collections, including Office 365 group-connected team sites and OneDrive. SharePoint admins can manually set lower storage limits.
5 Firstline workers can't administer SharePoint site collections.
6 Not including the OneDrive created for each licensed user.
7 If you have more than 500,000 users, please contact a Microsoft representative.

Service limits for all plans

  • Items in lists and libraries - A list can have up to 30 million items and a library can have up to 30 million files and folders. After 100,000 items are added to a list, library, or folder, permission inheritance for the list, library, or folder can't be changed. To learn more about other restrictions for viewing large lists, see Manage large lists and libraries in Office 365.

  • File size and file path length - 15 GB. The maximum size for files attached to list items is 250 MB. To learn more about restrictions and limits when using the new OneDrive sync client (OneDrive.exe), see Invalid file names and file types.

  • Moving and copying across site collections – 100 GB per operation. The web browser must remain open.

  • Sync - For optimum performance, we recommend storing no more than 300,000 files across all synced document libraries, even if you're using Files On-Demand or choosing only some folders within the libraries to sync.

    If you use the previous OneDrive for Business sync client (Groove.exe), you can sync up to 20,000 items total across all synchronized libraries. This includes OneDrive for Business libraries, team site libraries, or both. Separately from the overall sync limit, there are limits to the number of items that can be synchronized for each library type:

    • You can sync up to 20,000 items in a OneDrive for Business library. This includes folders and files.
    • You can sync up to 5,000 items in a SharePoint library. This includes folders and files. These are libraries that you find on various SharePoint sites, such as team sites and community sites, libraries that other people created, or that you created from your Sites page. You can sync multiple SharePoint libraries. Any team sites that you sync will also count against the overall 20,000 item limit across all synchronized libraries.


    If users need to sync files in document libraries that have hundreds of thousands of files, you can "hide" folders from the sync client by setting the permission level of the folders to "Restricted Read."

  • Versions - 50,000 major versions and 511 minor versions.

  • SharePoint groups - A user can belong to 5,000 groups, and each group can have up to 5,000 users. You can have up to 10,000 groups per site collection.


    For Azure AD group limits, see Azure AD service limits and restrictions as such limits can impact public and private group sites membership management.

  • Managed metadata - 200,000 terms in Term Store, 1,000 global term sets, 1,000 groups.

  • Subsites - 2,000 per site collection.

  • SharePoint hosted applications - 20,000 instances per organization.

  • Unique security scopes per list or library - The enforced limit is 50,000, but the recommended general limit is 5,000. Above 5,000, access control list (ACL) size starts to matter. Although you can add scopes up to the enforced limit of 50,000, Microsoft doesn’t recommend it unless you have a very specific scenario in mind. For large lists, design to have as few unique permissions as possible.

  • Users - 2 million per site collection.


    There is no limit to the number of guests you can invite to SharePoint site collections. For more information about external sharing, see External sharing overview.
