Email OTP not working for guest users
We have to enable MFA using Email for some guest users accessing some of our Entra applications. Guest users are from other Microsoft tenants, B2B collaboration users. We have it all set up in the Authentication methods and in Conditional access policies. Also excluded this user's security group from System-preferred multifactor authentication. When the guest user connects to the application or to the tenant portal, it's still prompting to register for MFA using authenticator App. how can we make it to use an email one-time code please ?

I think it's not possible since it's a B2B Collaboration account in a different 365 Entra domain. But any other suggestions welcome :-)
