Windows and Xbox Program Enrollment Failure – OAuth Error

I am writing to report an issue with enrolling in the Windows and Xbox program through Partner Center. When attempting to enroll in the "Windows and Xbox" program from Partner Center, the page redirects to a Microsoft Account OAuth error page with the following message: "We're unable to complete your request – unauthorized_client: The client does not exist or is not enabled for consumers. If you are the application developer, configure a new application through the App Registrations in the Azure Portal at https://go.microsoft.com/fwlink/?linkid=2083908." I have tried multiple browsers, cleared cache and cookies, and attempted enrollment several times — the error persists. This appears to be a known, widespread issue. Could you please assist in resolving this enrollment issue for our account, or provide an estimated timeline for a fix? Thank you for your time and support. I look forward to your response.

    The OAuth error during Windows and Xbox program enrollment cannot be fixed from the client side and requires Partner Center support intervention.

    Before contacting support, confirm the following basics that can block access to specific Partner Center workspaces:

    1. Verify roles and access in Partner Center
      1. Sign in to Partner Center and select the Settings (gear) icon.
      2. Go to Account settings → My access.
      3. Under Request access and help, confirm that the organization has access to Windows and Xbox and that the account has been added with the appropriate Owner/Manager role for developer programs.
      4. If not listed or access is missing, contact the person in the Owner or Manager role in the organization to grant access to the Windows and Xbox workspace.
    2. Confirm correct account and tenant
      1. Ensure sign-in is with the work account associated with the organization’s Partner Center account (not a personal Microsoft account) when accessing Windows and Xbox.
      2. If the account is in multiple Microsoft Entra tenants, make sure the tenant associated with the Partner Center account is selected when accessing secure Xbox/Windows resources.
    3. If pages/capabilities still fail with OAuth/unauthorized_client Since the error indicates a backend application configuration problem (client not existing or not enabled for consumers) and the issue persists across browsers and attempts, it must be handled by Microsoft support for Partner Center. Open a Partner Center support request and include:
      • The exact error text: unauthorized_client: The client does not exist or is not enabled for consumers.
      • The Partner Center workspace and step where the error occurs (enrolling in Windows and Xbox program).
      • Tenant ID, Partner Center account ID, and timestamps of recent failed attempts.
      Support can:
      • Validate the Partner Center account and Windows/Xbox program configuration.
      • Check and correct the backend application/registration used by the enrollment flow.
      • Provide status and, if applicable, an ETA or workaround.

    If the account is new and not yet fully verified, also check the Legal info page in Partner Center to ensure organization verification is completed; incomplete verification can block some Partner Center functionalities until support resolves it.
