crpb gmail doesn't seems to allow to display accounts separately, but yes, you're right, outlook or bluemail are working fine with exchange, they just need us to enter domain, mail server and username.
Emclient works too but display errors every minutes for no visible reason (it still correctly displays all mails)
Problem is, my family chose the mail client that they like, I won't force them to use something in particular, so I had to make maximum compatibility^^ Me and my father told them how great exchange was but they don't care.
Plus, if I later buy a licence to sell grommunio to customers, I have to make sure that it works with most of mail clients.
To sum it up: my family is the test population to later sell grommunio to customers, but they have their old habits and don't care about exchange, so I have to satisfy that
