Auto configure the mail clients Microsoft Outlook in the domain with the substitution account?
Haven't tried, but realized that the mail server settings are distributed via autodiscover. How to distribute centralized account settings for Outlook? So he did not asked to configure anything. And immediately start with the account the account currently active on the computer domain? Really is?
If the mail server is Exchange, the auto account works only on computers that are domain members. So when you first run the client, the box was sticking on their own without any action, you need to configure GPO (User Configuration -> Administrative Templates -> Microsoft Office Outlook 2007 -> Tools \ Account Settings -> Exchange “Automatically configure profile based on Active Directory Primary SMTP address” or whatever it is in Russian) or key in the registry (different versions of Outlook, your).
If you are using another mail server - unfortunately, the data have to drive handles.
