The issue has been reproduced in two fully independent Business Central Online tenants:
- Tenant A — cross-tenant configuration (BC and SharePoint in separate Microsoft 365 tenants)
- Tenant B — single-tenant configuration (BC and SharePoint in the same Microsoft 365 tenant)
Standard consent flow via "Set up service integration" → AADSTS7000119: "Client application '...' is not allowed to be used by tenant '...'"
Manually constructed admin consent URL following the guidance in KB AADSTS650056, Solution 3 → AADSTS7000118: "Resource application '...' is not allowed to be used by tenant '...'"
No service principal for App ID 21ca0e34-f076-4570-9900-caaaefd1062b is created in either tenant — consistent with the consent flow being blocked before provisioning.
According to the Microsoft Entra error code reference and independent technical sources, AADSTS7000119 and AADSTS7000118 are the expected error codes when an app registration is configured with signInAudienceRestrictions.allowedTenantsAudience and the requesting tenant is not on the allowedTenantIds list.
Because the behavior is identical across two independent tenants, it appears the app registration 21ca0e34-f076-4570-9900-caaaefd1062b has such an allowlist configured on the Microsoft side, and regular BC customer tenants are not included.
- Is "Business Central – Graph Integration" (App ID 21ca0e34-f076-4570-9900-caaaefd1062b) a Microsoft first-party application used by the E-Document Connector – Microsoft 365?
- Does this app registration have a tenant allowlist (signInAudienceRestrictions.allowedTenantsAudience) that prevents provisioning in customer tenants? If so, what is the intended process for BC customers to enable the SharePoint service integration?
- Is the SharePoint service integration in E-Document Connector – Microsoft 365 (version 28.2.50931.51529) generally available, or is it a preview with limited rollout?
- Is this a known issue or regression in Business Central 28.2 or in this connector version?
- Is there a recommended workaround until a resolution is available?
- Tenant A — cross-tenant configuration (BC and SharePoint in separate Microsoft 365 tenants)
- Tenant B — single-tenant configuration (BC and SharePoint in the same Microsoft 365 tenant)
