Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Nicolas,
Welcome to the Microsoft Community.
Regarding your query about "conditional access policy", hope your kind understanding that this query is required support from Azure support team which is different from us.
I would recommend you raise a support case with Azure, a Support Engineer will be able to look into this conditional access policy issue and assist you better.
You can raise support ticket from New support request - Microsoft Entra admin center or https://admin.microsoft.com/#/support/requests.
Hope this helps.
Best regards,
