exchange2016 access adfs2016 login

If the exchange server and the adfs server want to communicate with each other, which ports need to be opened?

For example, which ports will be requested for a login to exchange to adfs, and which ports will be requested for adfs to exchange, and will ad requests be involved in the middle? If so, which ports will be involved?

    The Exchange Servers do not communicate with the ADFS servers.
    The clients need to be able to connect on port 443 (and port 49443 for cert auth)

    Note only EAC and OWA support ADFS auth
