Automatically configure profile based on Active Directory Primary SMTP address
This policy setting controls whether users who are joined to a domain in an Active Directory environment can change the primary SMTP address that is used when they set up accounts in Outlook.
If this policy setting is enabled, users can create a new profile by entering a profile name. The profile is created without using the New Account wizard. No user interface appears as the profile is created, which might cause users to think that the computer has crashed.
If you disable or do not configure this policy setting, users joined to a domain in an Active Directory environment, and without a configured email account, see the current logged in user's primary SMTP address entered in the email address box in the New Account wizard. The email address can be changed to configure a different account. Or, if Next is clicked, the default settings are used.
