Explanation

Only Guest3 will receive a one-time passcode because the Email One-Time Passcode (OTP) feature activates specifically for guest users who cannot be authenticated through other means such as Azure AD, Microsoft Account (MSA), or Google federation. Guest1 and Guest2 likely have accounts that can authenticate via Azure AD or MSA, whereas Guest3 uses a domain that doesn't support any of these federated identity providers, making OTP the fallback mechanism. Azure AD one-time passcodes are valid for 30 minutes by default, after which the guest user must request a new code to complete authentication.
