Connection between Age of Empires 2 HD and Age of Empires II: Definitive Edition

Good morning, my question is about the compatibility of online playing of these two editions. I have one of them and a friend of mine the other, we have tried to create an online game but we do not see each other, if we see each other on steam. Is it possible to play in multiplayer with these two versions?

Nope. You need to both be playing on HD or both be playing DE.
