When you run the Catalog task to create a database catalog (CATALOG.NSF) from the CATALOG.NTF template, all databases in your organization are listed in the catalog. You can exclude mail databases from the catalog's default views by changing the database properties for each mail database. Excluding a database from a catalog's default views does not prevent administrators from creating views that display a complete listing of databases on the server.
Note: Because of ACL setting permissions, the Catalog task, and not a client's CATALOG.NTF, should always be used to create a database catalog.
