Add more SharePoint storage to your subscription

  • Άρθρο

If you start to run out of storage for your SharePoint sites, you can use the Office 365 Extra File Storage add-on to add more storage in 1 GB increments. You buy the add-on in the Microsoft 365 admin center. If you don't see the Office 365 Extra File Storage in the list of available add-ons, it means that your plan isn't eligible to buy it. For more information, see Is my plan eligible?

Note

If you bought your subscription through Volume Licensing or a Cloud Solution Provider (CSP), you can't buy Office 365 Extra File Storage directly from Microsoft. Contact your representative or partner for help. For information about OneDrive storage, see Set the default storage space for OneDrive users.

Before you begin

Note

If you're the person who signed up for the subscription, you're automatically a Billing account owner.

View available storage

In the SharePoint admin center, go to Active sites, and sign in with an account that has admin permissions for your organization.

The upper right side of the page shows the amount of storage used across all sites, and the total storage for your subscription. If your organization has configured Multi-Geo in Microsoft 365, the bar also shows the amount of storage used across all geo locations.

Note

The storage used doesn't include changes made within the last 24-48 hours. SharePoint storage is calculated in binary Gigabytes (GB), where 1 GB = 230 bytes.

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 costs to add storage space, follow the steps in this article and review the pricing information before you buy more.
