A GroupWise group is group that you, as the GroupWise administrator, create to facilitate easier addressing within your GroupWise system. Each group that you want to create must be added as a Group object in the GroupWise Administration Console. The name that you give the Group object becomes the name by which the group is displayed in the GroupWise Address Book.
A group can consist of users, resources, and other groups. Members do not need to be in the same post office as the group’s post office.
Because a group is an addressable entity, you must assign it to a post office when you create it. Regardless of the group’s post office, all GroupWise users can use the group when addressing a message.
