I will be moving two mail domains from hosting companies to manage inhouse, along with my current domain. I'm wondering what the best way is to add those, and how OWA will work. Currently we use https://mail.domain/exchange
for OWA. If I add two domains via the default recipient policy, will they also have to use the same OWA address? The two new domains will almost entirely use OWA for mail.
Just wondering what the best solution is, as the three domains are separate business entities and it will be odd having one log in with a different business domain name.
