Commercial Marketplace enrollment fails with 409 Conflict, and I can't open a support ticket (no workspaces)

Open a Partner Center support ticket without signing in, which bypasses the workspace-dependent Help + support form and is the documented route when Partner Center access is unavailable.^1^

Submit the enrollment case

1. Open the support link above in a private browser window and remain signed out of Partner Center.
2. Under Tell us about your issue, select:
   • General
   • Accounts, Onboarding, Access
   • Unable to Login to Partner Center
3. Select Provide issue details after reviewing the suggested solutions. This is the documented external support flow when Partner Center cannot be accessed.^2^
4. In the description, ask for routing to Commercial Marketplace enrollment/onboarding support. Marketplace onboarding and Partner Center account problems are handled through Partner Center support.^3^
5. Include:
   • Exact message: “The request could not be completed”
   • HTTP status: 409 Conflict
   • The two correlation IDs and their UTC timestamps
   • Your Microsoft Entra tenant ID
   • Registered legal company name, country/region, and company domain
   • The work account used for the latest attempt
   • A note that no Partner Center workspace or partner account was created
   • Screenshots of the final enrollment failure, empty workspace list, and authorization message
   • A note that an earlier attempt used a personal Microsoft account and might have created an incomplete or duplicate enrollment

Correlation IDs, tenant IDs, and company documents should be supplied only through the private support case, not posted publicly.

A suitable case summary is:

Commercial Marketplace new-partner enrollment fails after Accept and continue with “The request could not be completed” and HTTP 409 Conflict. No Partner Center workspaces were created, so the signed-in support form cannot be used. A previous attempt was made with a personal Microsoft account. Please check for an incomplete or duplicate enrollment associated with our legal entity, domain, tenant, or personal account and route this case to Commercial Marketplace enrollment support.

Before attempting enrollment again

Do not repeatedly submit a new enrollment while the support team investigates the possible earlier record. The 409 response alone does not establish that a duplicate or partial enrollment exists.

For a new Commercial Marketplace publisher, Microsoft requires:

• A Microsoft Entra work account, not merely a personal Microsoft account.
• Enrollment in the Microsoft AI Cloud Partner Program (MAICPP); new partners normally complete MAICPP and Commercial Marketplace enrollment through the combined flow.
• A Global Administrator to start a new MAICPP enrollment.
• The authority and business documentation required for legal verification.^4^

Partner Center explicitly distinguishes personal and work accounts that may display the same email address. When support clears or identifies the enrollment state, restart only with the organization’s Entra work account and verify that the displayed company, tenant, and country/region are correct before accepting the agreements.^1^

If support determines that an account was created under the wrong identity, it must handle the correction or deletion. Microsoft Marketplace accounts cannot be deleted directly by the user; deletion requires a support request.^5^
