OneDrive storage quota locked at 10GB (UserSpecific) on M365 E5 Developer Tenant despite 5TB Tenant limit

Hello Microsoft Community,

I am experiencing an issue where a user's personal OneDrive for Business site is hard-capped at 10 GB on a Microsoft 365 E5 Developer tenant. I am unable to increase this quota via the Microsoft 365 Admin Center or SharePoint Online PowerShell, despite the overall tenant limit being configured to 5 TB.

Below are the full technical diagnostics and steps already taken.

1. Environment & License Status

Tenant Type: Microsoft 365 Developer Program (E5 Developer Sandbox)

Assigned Licenses:

Microsoft 365 E5 Developer (without Windows and Audio Conferencing) — 78/78 services active, including SharePoint Plan 2 and Office Online.

  `Microsoft Power Automate Free` — 2/2 services active.
  
  __User Account Status:__ `Active` / `Member`

2. Symptoms & Observed Behavior

OneDrive Web Interface:

The storage meter reports: 10485.21% (over 1 TB used of 10 GB).

  The account is locked in read-only mode due to exceeding the quota.
  
  __Microsoft 365 Admin Center:__
  
     Navigating to __Active Users > [User] > OneDrive > Edit storage used__.
     
        Under manual storage allocation, the form triggers a hard validation error in red:
        
        _"Hạn mức dung lượng tối đa cho người dùng này là 10 GB"_ _(Maximum storage limit for this user is 10 GB)_.

3. PowerShell Diagnostic Outputs

Connecting to SharePoint Online Admin PowerShell yields the following configuration:

Tenant-level Storage Limit:

PowerShell

Get-SPOTenant

Output:

OneDriveStorageQuota: 5242880 (5 TB)

  `ManageUserStoragePolicies`: _(Empty/Disabled)_
  
  __Personal Site Status:__
  
  PowerShell
  
  ```yaml
  Get-SPOSite
  ```
  
  __Output:__
  
     `StorageQuota`: `10240` (10 GB)
     
        `StorageQuotaWarningLevel`: `9216` (9 GB)
        
           `LockState`: `Unlock`
           
              `Status`: `Active`
              
                 `StorageQuotaType`: `UserSpecific`

4. Troubleshooting Steps Attempted

PowerShell Set-SPOSite: Executed:

PowerShell

Set-SPOSite

Result: The command finishes with exit code 0 (no errors displayed), but running Get-SPOSite shows StorageQuota remains stuck at 10240.

Audit Log Inspection: Verified Entra ID Audit Logs for the user. No license or role changes occurred prior to the issue; only MFA/Authenticator token refresh events were logged.

5. Request

Because the site is flagged with StorageQuotaType: UserSpecific at 10240 MB, backend provisioning rejects any quota increase above 10 GB.

Could someone from the engineering or support team advise:

Is there a PowerShell parameter or backend procedure to clear the UserSpecific restriction and revert the site to inherit the 5TB tenant default?

Does Microsoft apply an automated backend throttle/cap (10 GB) to individual OneDrive sites on E5 Developer tenants once data thresholds are reached?

    Hi,

    This is expected behavior, since Microsoft has downgraded OneDrive storage limits for E5 for developer subscriptions.

    According to Microsoft (https://learn.microsoft.com/en-us/office/developer-program/microsoft-365-developer-program-faq#how-much-storage-does-the-microsoft-365-developer-subscription-provide-), there will be a 10 GB per user OneDrive limit and a tenant limit of 300 GB.

    Your files become read-only if you pass beyond that limit, and you can only edit or add files if storage is reduced back within the limit.

    Dear @Thắng Vũ,

    I hope you’re having a good day. 

    Thank you for the exceptionally detailed diagnostics. The information you've provided is very helpful and already rules out many of the common causes.

    Based on your findings:

    • The user has a valid Microsoft 365 E5 Developer license with SharePoint services enabled.
    • The tenant-level OneDrive quota is correctly configured at 5 TB.
    • The affected OneDrive site remains fixed at:
      • StorageQuota = 10240
      • StorageQuotaType = UserSpecific
    • Both the Microsoft 365 Admin Center and Set-SPOSite are unable to increase the quota beyond 10 GB.

    Given those results, this does not appear to be a simple tenant configuration issue or a PowerShell syntax issue. The behavior suggests that the 10 GB limit is being enforced at the service/backend level for this particular OneDrive site.

    At this point, the most likely possibilities are:

    • The OneDrive site is stuck in a UserSpecific quota state.
    • A backend quota enforcement process is overriding administrative changes.
    • A Developer Program entitlement or provisioning issue is affecting the site.
    • A service-side issue specific to this OneDrive site.

    Since both the Admin Center and PowerShell are being overridden, I believe this has reached the point where Microsoft Support should investigate the backend configuration of the OneDrive site.

    You can raise support ticket from Microsoft 365 Admin Center>Support>Help & Support.   

    For reference:  Get support | Microsoft Docs

    The good news is that you've already gathered most of the diagnostic information Support would typically request, including tenant configuration, licensing details, Admin Center behavior, and PowerShell outputs. That should help accelerate the investigation.

    Thank you again for the thorough testing and documentation. You've done an excellent job narrowing down the scope of the problem.

    If you receive any findings from Microsoft Support, please feel free to share them here.

    Warm regards,
