This policy setting controls whether a user's Active Directory Primary SMTP address is automatically used when any new profile is created.
If you enable this policy setting, when a user creates any new profile, the user's Active Directory Primary SMTP address is used for the profile. The user can only enter a profile name. The wizard used to configure specific profile settings is not shown to the user as the profile is created.
Note: If you want only the first new profile to use the Active Directory Primary SMTP address, and allow the user to specify a different SMTP address when creating other profiles, then use the "Automatically configure profile based on Active Directory Primary SMTP address (one-time only)" policy setting instead.
If you disable or don't configure this policy setting, when a user creates a new profile, the wizard used to configure specific profile settings is shown to the user and the user can specify any SMTP address as the profile is created.
