A dynamic distribution group is a mail-enabled Active Directory group object that you can create to expedite the mass sending of email messages and other information.
The membership list for a dynamic distribution group is calculated each time a message is sent to the group, based on the filters and conditions that you define. This differs from a regular distribution group, which contains a defined set of members. When an email message is sent to a dynamic distribution group, it is delivered to all recipients in the organization that match the criteria defined for that group.
