Adding two separate mail domains - best way to access OWA


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.

All the users will need an smtp address in the existing domain, that will stop OWA for all the users breaking badly. You can indeed add/edit the recipient policy and filter it to include the users you need.

Unless you're talking lots of users then I'd leave it so that you use one URL. If you are really adamant the easiest way is to register a new domain name "generic.com" and then get a new certificate called "mail.generic.com"

Believe me or no, you will find that to be the quickest and least complex solution and the easiest to manage. The outlay for the new domain and certificate are tiny compared to the hours (and time is money) you'd need to spend crafting new websites, getting several URL specific certificates and then making sure that each user got the right URL with the right corporate branding.
I agree with czcdct, creating a new generic domain name and using that is the best way to go about this.
