1 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. 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 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), the sync limit per library is 20,000 items (including 5,000 items per team site).
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.
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 - 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 guests you can invite to SharePoint site collections. For more information about external sharing, see External sharing overview.
