Subscriptions with less than five users receive 1 TB of personal cloud storage per user.

Customers will initially be provisioned 1 TB of personal cloud storage per user in OneDrive for Business. You may increase the default OneDrive for Business storage space to up to 5 TB per user with the help of your Office 365 administrator once the 1TB quota is 90% full.


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

Whenever you need cloud storage beyond the initial 5 TB, 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 for Business storage to at least 90% capacity, Microsoft will increase your default storage space in OneDrive for Business to up to 25 TB per user (admins may set a lower per user limit if they wish to).

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

To see how much personal cloud storage you are using, your Office 365 administrator can go to the OneDrive Admin Center to manage their users' personal cloud storage.

See Change your users' OneDrive storage space using PowerShell for more information on how Office 365 administrators can manage user storage in OneDrive for Business.

Supported uses

With OneDrive for Business, every person can easily store, access, and share their work files in their personal online storage space in the cloud. OneDrive for Business 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's personal 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 for Business limitations

OneDrive for Business is included in SharePoint Online. To learn about limitations such as file upload limits and site collection quotas see SharePoint Online limits and Restrictions and limitations when you sync files and folders.

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