AADSTS700016 🔷 Azure

Azure AD (Entra ID): AADSTS700016 Application not found in the directory

The client ID in your sign-in request doesn’t exist in the tenant you’re authenticating against.

Seen on: Azure

Meaning

Either the app ID is wrong, the app is registered in a different tenant, or a multi-tenant app hasn’t been consented in the user’s tenant.

Common causes

  • Wrong client/application ID
  • Using a tenant-specific authority for a different tenant
  • Single-tenant app used by external users
  • App registration deleted

⚡ Quick fix

  1. Verify the Application (client) ID in Entra ID → App registrations
  2. Use the right authority (/common, /organizations or the tenant ID)
  3. Make the app multi-tenant if external users sign in
