Add storage space for your subscription
If you start to run out of storage for your SharePoint Online site collections, you can add storage to your subscription if your plan is eligible. If you don't see the Office 365 Extra File Storage in the list of available add-ons, it means your plan is not eligible. For more information, see Is my plan eligible?
If you bought your subscription through Volume Licensing or a CSP, you can't buy Office 365 Extra File Storage for your organization directly from Microsoft. Contact your representative or partner for help.
Before you begin
You must be a Global or SharePoint admin to do the tasks in this article. For more information, see About admin roles.
View available storage
In the upper right of the page, see the amount of storage used across all sites, and the total storage for your subscription. If your organization has configured Multi-Geo in Office 365, the bar also shows the amount of storage used across all geo locations.
The storage used doesn't include changes made within the last 24-48 hours.
After you determine how much storage you're using, you can add or remove storage space for your subscription. To find out how much it will cost to add storage space, follow the steps in this article, and review the pricing information before you buy more.
For information about setting site collection storage limits, see Manage site collection storage limits.
