Warning before sending an email with no/1.0/1.1 TLS

Occasional Visitor

Is there any way a sender of an email using Outlook 365 can be warned immediately that the recipient does not support TLS 1.2?


By any way, I mean is anybody aware of a native feature or add-ins/third party plugins?

@HippoKant , could you explain why do you need this feature?
