Other features or issues related to Microsoft Partner Center
Hi Pepijn,
The 715-123160 message indicates that the Partner Center enrollment was blocked during Microsoft's trust/verification process. There is no self-service option to override this check. Similar cases report the same issue where the enrollment is blocked before a Partner Center workspace is created.
Since you cannot open a Partner Center ticket without a workspace, use the Partner Center support channel and provide the reference number and correlation ID, requesting a manual review of the blocked enrollment. Microsoft's documentation confirms Partner Center support handles enrollment and account issues.
I would also avoid repeatedly submitting the enrollment, as that can make troubleshooting harder. Include your company legal details and the exact error shown on the enrollment page.
