I have a server with Exchange 2019
with two accepted domains : ex. domain1.com and domain2.com

when I add a new user in AD, or in Exchange admin,
the new user has automatically assigned the email with domain1.com

how do I make sure that the mailbox is on domain2 instead?
neither in edit user I can't change default mailbox.

sorry but sysadmin leaves and i never managed exchange servers.

    See my answer above:

    If you cant change the default email address, uncheck this option, save, then set the new default address
