Summary: Microsoft 365 offers various applications including SharePoint Online for content management and collaboration. To check storage details in SharePoint Online, you can use the SharePoint admin center to view storage metrics for each site. Additionally, you can use Windows PowerShell to connect to SharePoint Online and retrieve storage quota information for all sites in your account. These methods allow administrators to monitor and manage storage effectively.

Microsoft 365 offers a suite of applications, including Exchange Online, OneDrive, SharePoint, and more. Among these, SharePoint Online stands out as a cloud-based service that empowers users to efficiently manage diverse content and foster collaboration. The available storage capacity for your SharePoint Online account depends on your subscription plan and the number of licenses you hold. SharePoint Online administrators frequently need to assess storage quotas and allocations for various purposes. In this guide, we will present several techniques for locating storage-related settings in SharePoint Online.

Ways to check SharePoint Online storage information

  1. Via SharePoint Online Admin Center
  2. Via Windows PowerShell
Check the storage space using the SharePoint admin center

How to check SharePoint Storage quota using Windows PowerShell?

To get the storage quota in your SharePoint Online, you can use the Windows PowerShell.

First of all, you require connecting SharePoint Online Site with Windows PowerShell. Let us know about its process.

  1. Run the Windows PowerShell as administrator by right-clicking it and selecting Run as administrator option.
  2. Then run this command.
    $credential = Get-Credential

    A dialogue box with credential req will be opened. Here, add your SharePoint Online account user name and password, then click OK.

  3. Then, to import the Windows PowerShell module, you need to run this command.
    Import-Module Microsoft.Online.SharePoint.PowerShell

    import the Windows PowerShell module

  4. Finally, execute the below command to connect SharePoint Online to PowerShell module.
    Connect-SPOService -Url https://”username” -credential $credential


  5. Hence, you have connected SharePoint Online to Windows PowerShell successfully. To check the storage quota of a particular SharePoint site, just run this command next.

    SharePoint Online to Windows PowerShell

You will get information like Site URL, Owner name, and Storage Quota for all sites available in that SharePoint Online account.

This manual procedure outlines how to determine the storage quota in SharePoint Online. While the Exchange Online PowerShell approach may appear somewhat technical, the first method offers a straightforward alternative. SharePoint Administrators should inform users about the manual process for checking SharePoint Storage information.

Setting automatic or manual site storage limits in SharePoint

In SharePoint, storage management is streamlined through a centralized pool, eliminating the need for Global Administrators or SharePoint Administrators to allocate specific storage quotas to individual sites. This automated approach allows sites to access the necessary storage from the pooled resources without manual intervention.

Initially, if the storage management is transitioned from manual to automatic (pooled storage), SharePoint automatically adjusts the storage limits of all sites to a substantial capacity of 25 TB (25,600 GB), subject to the total available storage for the organization potentially being less.

For organizations requiring a more granular control over storage allocation, the option to manually set storage limits for each site is available. This can be particularly useful for managing resources in a more tailored manner, ensuring critical sites have adequate storage while preventing excessive use by less critical sites.

Procedure for Managing Site Storage Limits
  • Navigate to the SharePoint admin center and authenticate using an administrator account. Locate and select ‘Site storage limits‘ within the Settings section.
  • From the available options, select either ‘Automatic‘ for pooled storage management or ‘Manual’ for individual site storage allocation. Confirm your selection by clicking ‘Save‘.Confirm your selection by clicking Save
Detailed steps for manual storage allocation

To assign specific storage limits under the manual setting, follow the below steps:

  • Site selection: Within the SharePoint admin center, proceed to ‘Active sites‘. Select the desired site from the list, or for channel sites, use the link provided in the ‘Channel sites‘ column.
  • Editing storage limits: On the site’s ‘General‘ tab, locate the ‘Storage limit‘ section and click ‘Edit‘. This action opens the panel for editing storage limits.Editing storage limits
  • Setting storage quota: Input the desired maximum storage capacity for the site in GB, noting that the maximum permissible value is 25,600 GB, which may exceed the total storage available to your organization.
  • Enable notifications: Ensure the ‘Notifications‘ feature is activated to allow for email alerts to site administrators when storage usage approaches the set limit. Specify the storage threshold as a percentage for when these notifications should be triggered.
  • Save changes: After configuring the storage limit and notification settings, click ‘Save‘ to apply the changes.

In instances where a site exhausts its allocated storage, site administrators have the option to request additional quota through the ‘Storage Metrics‘ section under ‘Site Collection Administration‘ within the Site Settings, thereby sending a notification to Global Administrators for action.

You must note that certain features and functionalities within SharePoint may be introduced progressively, especially to organizations enrolled in the Microsoft 365 Targeted release program, which may affect the visibility and appearance of the described features.
