Security and Distribution Domain Configurations

You must select one of two group types when you create a new group.

• Security Group Type

  Use security groups to manage user and computer access to shared resources and to control which users receive group policy settings.

• Distribution Group Type

  Use distribution groups as email distribution lists with email applications such as Microsoft Exchange or Microsoft Office Outlook. You cannot use distribution groups to assign permissions or to filter group policy settings.

  For this reason, a domain group configured as a distribution type rather than a security type cannot be used for security purposes.
