OneDrive for Business service description

OneDrive is online storage space in the cloud that's provided for individual licensed users in an organization. Use it to help protect work files and access them across multiple devices. OneDrive lets you share files and collaborate on documents, and sync files to your computer. Learn more about OneDrive features, functionality, and pricing.

OneDrive is included in Microsoft 365 and Office 365 plans, in SharePoint Online plans, and can also be purchased as a standalone plan.

To compare plans, see Compare Office 365 for Business plans and Compare OneDrive for Business plans.


OneDrive for Business standalone plans include Office for the web.

You must assign at least one license to a user before you can increase the default OneDrive storage space.

When you need cloud storage for individual users beyond the initial 5 TB, admins can open a case with Microsoft technical support to request it. Additional cloud storage will be granted as follows:

  • When a user has filled their 5 TB of OneDrive storage to at least 90% capacity, Microsoft will increase your default storage space in OneDrive to up to 25 TB per user (admins may set a lower per user limit if they want to).

  • For any user that reaches at least 90% capacity of their 25 TB of OneDrive storage, additional cloud storage will be provided as 25 TB SharePoint team sites to individual users. This additional storage is provided to the organization by way of credit.

To see the storage space and usage for an individual user, go to Manage storage in the OneDrive sync client. To see how much storage users across the organization are using, go to the OneDrive usage report in the Microsoft 365 admin center.

Supported uses

OneDrive storage is provisioned on a per user basis and is designed to serve the needs of individual users.

Storage of data other than an individual user's work files, including system back-ups and departmental and organizational level data, is not supported, nor is the assignment of a per user license to a bot, department, or other non-human entity. SharePoint is the best solution for more advanced content management and collaboration, including storing and managing files, communications, and intranet sites across a team or organization.

OneDrive limits

To learn about file and sync limits, see SharePoint Online limits and Invalid file names and file types.

For plans that include unlimited cloud storage for individual users, note that limits may apply on non-storage features.
