Is it possible to use an App Registration from a different tenant to create an indexer in Azure AI Search?

Hi team,

I’m working with two separate tenants:

Can I configure an indexer in Azure AI Search on Tenant A by leveraging the App Registration keys from Tenant B?

Or is it mandatory to use an App Registration from the same tenant where the AI Search service is hosted?

    Hi there preetham p

    Thanks for using QandA platform

    No, you cannot use an App Registration from Tenant B to create or manage indexers in an Azure AI Search service that exists in Tenant A. This is a security boundary enforced by Azure:Azure AI Search service is tied to the tenant it was created in (Tenant A in your case)

    Ref -https://learn.microsoft.com/en-us/answers/questions/2137988/can-i-use-other-tennant-app-registration-to-create

    If this helps kindly accept the answer thanks much.
