How to create a dynamic distribution group in Microsoft 365?
In Microsoft 365, dynamic distribution group members are determined by recipient filters and conditions rather than a static list. These email groups are useful when membership needs to be dynamic and based on specific attributes or criteria. You can reconfigure the settings at any time based on your needs, and the dynamic distribution group will automatically update its membership based on recipient filters.
