Hi there,
We have an Azure AD tenant there are quiet a few B2B guest accounts (some MSA, some on their own tenant). We also have a B2C tenant where we have implemented custom policies with multi-tenant azure ad claims provider (specific tenants, not any azure ad tenant). However, guest accounts to my Azure AD tenant can't login to B2C through the custom policy. If I use one of the builtin flows and add my Azure AD tenant as an OIDC provider, they can login. How can I enable similar experience with my custom policies?

    Currently this is not possible. To allow guests users to login you will need to individually configure each tenant.
