Automatically configure profile based on Active Directory Primary SMTP address
By default, if a user is joined to a domain in an Active Directory environment and does not have an e-mail account configured, Outlook populates the e-mail address field of the New Account Wizard with the primary SMTP address of the user currently logged on to Active Directory . The user can change the address and configure a different account, or click Next to configure the populated settings. By enabling this setting, you can change this behavior so that the user does not have the option to configure a different account. The account is automatically configured using their primary SMTP address without showing the New Account Wizard.
