Cross-tenant access - 'inherited' on a partner means it has no override and the Default row applies.

Required Microsoft Graph permissions

Policy.Read.All CrossTenantInformation.ReadBasic.All — application permissions, granted to the app registration with admin consent.

Endpoints: GET /v1.0/policies/crossTenantAccessPolicy/default · GET /v1.0/policies/crossTenantAccessPolicy/partners · GET /v1.0/tenantRelationships/findTenantInformationByTenantId (names)

CrossTenantInformation.ReadBasic.All is optional - without it partners are shown by tenant id.

If a permission is missing, this report shows a red load error with the Graph status code — not an empty table.

Cross-tenant Access & B2B Trust

Which external tenants can collaborate with yours, whose MFA and device-compliance claims your Conditional Access accepts, and where shared channels (B2B direct connect) are open. Trusting another tenant's device compliance means their Intune decides who is 'compliant' in yours.

No cross-tenant access policy was returned. Please contact support if this is not the expected result.
