Domain name

Good morning,

We are thinking of setting up an Active Directory from 0, and add it for mail issues to O365.

I have heard recently, that they advise to put the real name in the local domain, ie, formerly I could put ITPRO.local but if the mail domain I want to be itpro.com

Is it advisable to call my domain itpro.com to avoid problems?

Would it be a better practice?

Hi,

Routable(registered) vs Non-routable domains(non-registered), always debatable topic.

I would recommend to go for routable domain, considering office 365 domain user sync and ease of migration .
Also it makes easier for certificate management and etc.

.local will still work. But its not needed. Best practice is to use a subdomain of a TLD that your org controls. something like ad.itpro.com

Hi

Exactly, it would be a registered domain.

Would it be a better option to have an empty root domain and subdomains underneath than to have all the AD structure in the root domain?

Why?

Yeah that should be fine. Just mange your zones properly.

In recent times, Microsoft also suggest to work with TLD subdomains, within a publicly registered TLD domain.
