Microsoft Partner registration error

The error indicates a registration/verification block at the Partner Center stage, which must be resolved by Microsoft support. Because the workspace is not yet created, use the general Partner Center support path and, if needed, send diagnostics and follow escalation guidance from the documentation.

Actionable steps:

1. Retry registration with required details
   • Ensure the account type is Company and that the Publisher display name, company name, and legal documents (formation documents, government-issued license, etc.) are correct and match the D‑U‑N‑S information.
   • Follow the documented flow for opening a company developer/partner account starting from the registration page: join the appropriate program (for apps, typically Windows and Xbox or the relevant marketplace program) and complete all steps including payment and document upload.
   • If there is a known locale issue, manually set the browser locale to en-us before starting registration, as documented.
2. Use Partner Center support even without a workspace
   • When the registration error appears, if a Collect more information link is shown at the top of the page, select it to open the client diagnostic tool.
   • Save the diagnostics report to the local machine and review/redact any personal data.
   • Then go to Partner Center support (outside of the blocked registration flow) and create a support request, attaching the diagnostics file in Step 1 → Additional details of the support form.
   • If the UI insists on a workspace, choose any available generic option or “not applicable” if present, and clearly state in the ticket description that registration is blocked before workspace creation.
3. If support response is delayed
   • Support tickets are typically resolved within about a week. If there is no update after seven business days, send an email to the Teams submission escalation alias with:
     • Subject: “Partner Center Account Issue for your app name”
     • Body: support ticket number, seller ID (if available), and screenshots of the error.
4. If app creation is also blocked later
   • If, after registration is fixed, app creation in Partner Center fails with permission errors, verify in Microsoft Entra ID that:
     • Users can register applications is set to Yes under User settings.
     • The account has the Application developer role assigned under Roles and administrators.

These steps ensure Microsoft support receives the diagnostics and context needed to unblock the Partner registration and complete verification, which is required to remove the “Unverified app” warning for external users.
