After creating a post office, you can change some of the post office properties. Other post office properties cannot be changed.
In the GroupWise Administration Console, browse to and click the name of the post office.
Click the objects (Users, Groups, Resources, and so on) to list objects of each type that belong to the post office.
Click the system tools (Administrators, User Move Status, and so on) to use the tool specifically in the context of the selected post office.
Click the tabs (General, Settings, Client Settings, Security, and Internet Addressing) to configure those aspects of the post office.
Click Save, and then click Close to return to the main Administration Console window.
