3 When you have an Office 365 subscription and a SharePoint Online standalone plan, the storage amounts are added.
4 SharePoint Online administrators can set storage limits for site collections and sites.
5 Kiosk workers can't administer SharePoint Online site collections. You need at least one Enterprise user license to manage kiosk site collections.

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 100,00 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. For information about characters that can't be used in file names, see Invalid characters in file and folder names.

  • File size and file path length - 15 GB. To learn more about restrictions and limits when using the new OneDrive sync client (OneDrive.exe), see Invalid file names and file types in OneDrive, OneDrive for Business, and SharePoint.

  • 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 in a single OneDrive or team site library. Although SharePoint Online can store 30 million documents per library, for optimum performance we recommend syncing no more than 300,000 files across all document libraries. Additionally, the same performance issues can occur if you have 300,000 items or more across all libraries you are syncing, even if you are not syncing all items in those libraries. If you use the previous OneDrive for Business sync client (Groove.exe), the sync limit per library is 20,000 items (including 5,000 items per team site).

  • 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.

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

  • Subsites - Up to 2,000 per site collection.

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

  • Unique security scopes per list or library - 5,000. 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 external users you can invite to your SharePoint Online site collections. For more information, see Manage external sharing for your SharePoint Online environment.
