Exchange Distribution Group
Distribution groups are mail-enabled Active Directory directory service group objects that are created to expedite the mass sending of e-mail messages and other information within an Exchange organization.
Exchange 2007 supports the following types of distribution groups:
- Mail-enabled universal distribution groups These are Active Directory distribution group objects that are mail-enabled. They can be used only to distribute messages to a group of recipients.
- Mail-enabled universal security groups These are Active Directory security group objects that are mail-enabled. They can be used to grant access permissions to resources in Active Directory and can also be used to distribute messages.
- Mail-enabled non-universal groups These are Active Directory global or local group objects that are mail-enabled. In Exchange 2007, you can create or mail-enable only universal distribution groups. You may have mail-enabled groups that were migrated from previous versions of Exchange that are not universal groups. These groups can still be managed by using the Exchange Management Console or the Exchange Management Shell.
- Dynamic distribution groups These are distribution groups for which membership is based on specific recipient filters rather than a defined set of recipients. Dynamic distribution groups were called query-based distribution groups in Exchange 2003.
