Hi,
You need to use Exchange management tools like Exchange Admin Center and Exchange management shell to create mailboxes and it wouldn't be possible to create mailbox from Active directory.
While using EAC or EMS, you can create new mailboxes for existing AD accounts or create new AD accounts by specifying the organization unit.

I'm afraid this feature is not available with Exchange 2016 management tools. This was available in Exchange 2003 and has been removed from Exchange 2007. For managing mailboxes, we need to use Exchange management tools.
