Partner Center enrollment blocked – Trust Code 715-123160

Question

I'm an individual developer trying to register for the Commercial Marketplace program in Partner Center (to publish an Outlook Add-in via AppSource). During registration, after accepting the Publisher Agreement, I received this automated block: "Microsoft runs on trust. We engage in a rigorous set of evaluation and certification processes; as a result your request was blocked." Reference number: 715-123160 Transaction ID: 388c756e-bcbd-4b7d-b99d-16df6048b87c I tried to escalate this through Help + Support inside Partner Center, but the support request form requires selecting a "Workspace," and the dropdown shows "No results found" — because my Commercial Marketplace enrollment never completed, so no workspace was created. This creates a loop I can't get out of through the standard UI flow. My Partner Center account itself works fine (I'm Global admin), but Legal info and Identifiers are both empty, and the Commercial Marketplace program still shows "Get started" rather than any pending/in-progress state — so the registration attempt seems to have left no trace on Microsoft's side. Could someone manually review this and help me complete enrollment, or let me know what specifically caused the block? Thank you for your help.
