Hi, thank you for sharing the references.

I am still unclear on how this would work in practice since multi-tenant bots have been deprecated as of July 31, 2025. In that scenario, I am not sure how external tenant users would be able to authenticate and then upload files through the Agents SDK. Could you clarify what the recommended approach is for enabling cross-tenant file uploads now that multi-tenant registration is no longer supported?

    Hello @chetanoptimus, single tenant/multitenant only applies to the Azure Bot registration type and not the Entra/AAD app used for Bot creation. Entra app can continued to be created as Multi-Tenant (Accounts in any organizational directory (Any Azure AD tenant – Multitenant).

    Only for the "Type of App" in Azure bot registration, options are now limited to Single Tenant and User-Assigned Managed Identity.
