Automatically configure profile based on Active Directory Primary SMTP address (one-time only)
Verified with Microsoft 365/Office 5568.1000 — updated on September 4, 2026
Supported on: At least Windows Server 2008 R2 or Windows 7
Path in the GPO console
User Configuration\Administrative Templates\Microsoft Outlook 2016\Account Settings\Exchange Description
This policy setting controls whether a user can create additional profiles and specify a different SMTP address, after the first profile is automatically created using the user’s Active Directory Primary SMTP address. If you enable this policy setting, the first time a user creates a 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. After the first profile is created automatically, the user can manually create additional profiles. 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. Note: If you want the user’s Active Directory Primary SMTP address to always be used when creating a new profile, then use the “Automatically configure profile based on Active Directory Primary SMTP address” policy setting instead. If that policy setting is enabled, then it takes precedence over this policy setting. 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.
