Answer 1

To reach the Data Protection team when the usual IVR number is unavailable, use one of these supported paths:

1. Use the global customer service phone list
   • Go to the global phone numbers list for Microsoft support: Customer service phone numbers.
   • If the number for the country/region is unreachable or “switched off,” select a neighboring country/region from the same list, or use the United States support number as indicated in the documentation.
   • When connected to the IVR/agent, clearly state that this is a tenant lockout and that there is no other Global Administrator / glass-break account, and request escalation to the Data Protection team.
2. Use Microsoft 365 admin support (if any admin account is still usable)
   • If any admin account can still sign in, open the Microsoft 365 admin center, go to Support > Help & support, describe the issue as a Global Admin tenant lockout with no alternate GA, and request escalation to the Data Protection team.
3. If no admin can sign in and phone still fails, use a temporary trial tenant
   • Create a trial Microsoft 365 tenant (any business trial plan) to gain access to an admin center.
   • In that new tenant’s Microsoft 365 admin center, go to Support > Help & support and open a ticket explicitly stating:
     • This is for a different tenant where the only Global Admin is locked out.
     • The tenant domain and locked GA UPN.
     • That phone support numbers from the Customer service phone numbers page are not reachable.
   • Ask that the case be routed to the Data Protection team for tenant lockout recovery.
4. Partner-specific guidance (if acting as a partner)
   • For tenant lockout scenarios where the customer has no other GA and no usable GDAP access, the documented next step is: the tenant owner / end-customer Global Administrator must contact Microsoft support using the Microsoft 365 for business support phone numbers by country/region.
   • If the partner has GDAP with appropriate roles and can still access the tenant, work directly with the customer to restore access without involving Microsoft.

These are the supported escalation paths when a Global Admin is locked out and there is no glass-break account; all of them ultimately route through the global support phone list or an admin-center support ticket so the Data Protection team can verify identity and restore access.
