Suggession to imporve Active Directory
There should be an Active Directory Object for main office and other/field locations, Members tab to add bulk users and a drop-down menu in every user account to simply choose which office do they belong to as well. Also, it would be awesome to have a drop-down menu for every user account to bind with domain-joined or non-domain joined PC.
This makes Active Directory and User management way easier, System Administrators can also keep a track of assigned devices to every user, change the location details easily of course for bulk users by creating an office location object and adding multiple users into that location as members. I understand there are powershell scripts to complete bulk action - but still, as said, it makes AD look much more cleaner and could make management way more easier.
