Modern Authentication for Exchange Server 2019 on-premises supported?

Maker He 21 Reputation points

Hello All,

I'm trying enable Modern authentication for Exchange Server 2019 on-premises.

Background (in 2017):
in Channel9: (in video 23:30)
(direct video link:
The speaker said: On-Prem - Exchange Server 2019 Feature, with exchange on prim, adfs on prim. "We won't officially support that until the next version of exchange coming next year."

Anyone can help pass me some article / guide how to enable "Modern authentication" on-premises? It's exchange on prim, adfs on prim.

Thank you in advance!

    @Marco Schiavon Thank you for your reply, but that's not answer my question.
    I'm seeking a solution (or workaround) how to build Modern Authentication on-premises, Exchange Server on-premises and also ADFS on-premises.
    Due to my working environment only have limited internet bandwidth, non stable connectivity. Cannot use HMA.

    The Exchange 2019 doesn't support the pure "Modern authentication" so far. You still need to use HMA, if you want to apply MA for Exchange on-premises.

    Here is the Exchange Team Blog. If pure Exchange on-premises supports the MA, there will exist a blog from Exchange team. Let's wait together.
