Hi @NorthernApe
If you can't delete the organization
When you configured your Azure AD organization, you may have also activated license-based subscriptions for your organization like Azure AD Premium P2, Microsoft 365 Business Standard, or Enterprise Mobility + Security E5. To avoid accidental data loss, you can't delete a organization until the subscriptions are fully deleted. The subscriptions must be in a Deprovisioned state to allow organization deletion. An Expired or Canceled subscription moves to the Disabled state, and the final stage is the Deprovisioned state.
