Change a specific user's OneDrive storage space

  • Article

As an IT administrator, you can adjust a user's OneDrive storage space using the SharePoint admin center or PowerShell.

Note

For setting the default storage space for all users, see Set the default storage space for OneDrive users. For details on available storage for your Microsoft 365 subscription, see the OneDrive service description.

Important

If a user has run out of storage, advise them to proactively review and manage their storage. Instructions can be found at Manage your OneDrive for work.

Change storage space in the Microsoft 365 admin center

  1. Sign in to the Microsoft 365 admin center with your admin credentials.

    Note

    For Office 365 operated by 21Vianet (China), sign in here.

  2. In the left pane, expand Users and select Active users.

  3. Select the user whose storage you want to change.

  4. Go to the OneDrive tab.

  5. Under Storage used, select Edit.

  6. Choose the Maximum storage for this user option and set the storage limit.

  7. Select Save.

When users need more storage beyond the initial 5 TB, Microsoft increases their storage as follows:

  • When a user reaches 90% of their 5 TB capacity, Microsoft increases their storage to up to 25 TB. Admins can set a lower limit if desired.

  • If usage drops below 90%, storage limit resets to 5 TB.

  • For users reaching 90% of their 25 TB capacity, more storage is provided via SharePoint team sites. Contact Microsoft Support for assistance.

    Note

    For Office 365 A1 users, storage is limited to 100 GB. For more information, see Office 365 Education service descriptions.

Change storage space using PowerShell

  1. Download the latest SharePoint Online Management Shell.

    Note

    Uninstall any previous versions of the SharePoint Online Management Shell before installing the latest version.

  2. Save the following PowerShell script to a file (for example, you can save it as UpdateOneDriveStorage.ps1):

    $TenantUrl = Read-Host "Enter the SharePoint admin center URL"
Connect-SPOService -Url $TenantUrl

$OneDriveSite = Read-Host "Enter the OneDrive Site URL"
$OneDriveStorageQuota = Read-Host "Enter the OneDrive Storage Quota in MB"
$OneDriveStorageQuotaWarningLevel = Read-Host "Enter the OneDrive Storage Quota Warning Level in MB"
Set-SPOSite -Identity $OneDriveSite -StorageQuota $OneDriveStorageQuota -StorageQuotaWarningLevel $OneDriveStorageQuotaWarningLevel
Write-Host "Done"

  3. Open the SharePoint Online Management Shell and run the script:

    PS C:\>.\UpdateOneDriveStorage.ps1

    Note

    If you receive an error regarding script execution, you may need to adjust your PowerShell execution policies. For more information, see About execution policies.

  4. Enter the required values when prompted, including:

    • The SharePoint admin center URL (for example, https://contoso-admin.sharepoint.com)
    • The OneDrive site URL (for example, https://contoso-my.sharepoint.com/personal/user_contoso_onmicrosoft_com)
    • Storage Quota in MB
    • Storage Quota Warning Level in MB

Here's a reference table for MB to TB conversions:

MB TB
1,048,576 1
2,097,152 2
3,145,728 3
4,194,304 4
5,242,880 5

Note

To change storage space for multiple users, you can list OneDrive accounts via PowerShell and use the Set-SPOSite command to apply changes.

Troubleshooting OneDrive storage issues

If you encounter issues when adjusting storage or if the storage amount reverts to its original value, a Microsoft 365 administrator can run diagnostics in the admin center.

  1. In the Microsoft 365 admin center, select Run Tests to launch the OneDrive storage quota diagnostic.

    Note

    Diagnostics are unavailable for GCC High, DoD, Microsoft 365 operated by 21Vianet, or Microsoft 365 Education.

  2. Follow the recommendations provided by the diagnostic.

    Note
