Microsoft Outlook is the email application within Microsoft Office. On the company network, your Exchange account will autoconfigure if you are using a domain workstation and are logged into the domain with the same Active Directory account that corresponds to your email. Just open Outlook and everything will set itself up for you.
If you are installing your Exchange account on a non-domain workstation, your account will still auto-configure using the Active Directory and DNS autodiscover service. Just follow these simple steps.
