How to recover global admin access to tenant

This requires Microsoft’s tenant recovery process; neither a guest user nor the former employee’s credentials can be used to bypass ownership verification. Contact Microsoft Support, state “Microsoft Entra tenant lockout with no accessible Global Administrator,” and request escalation to the Data Protection or Tenant Recovery team, providing the tenant ID, subscription or billing evidence, company documentation, and proof of domain ownership privately. If the subscriptions are CSP managed, the CSP must open the Microsoft support case through its partner support channel. After recovery, create at least two organization controlled emergency Global Administrator accounts, because each Microsoft Entra directory is separate and administrators in your other directories cannot recover this one.
