You can select which address books you want to use when adding invitees to Agenda entries and when searching for people. The Oracle Calendar directory is always used.
The Global Address List (also referred to as the GAL) contains all calendar users, resources, and event calendars on the calendar server. It may also include non-calendar users. By default, the GAL is downloaded every seven days. However, this is a server-side parameter that can be modified by an administrator.
Your personal address book contains all your contacts, and is also available for offline use. By default, it is available when you launch the Oracle Calendar desktop client. If you prefer not to use your personal address book, deselect Personal Address Book.
NOTE: Enable searching for invitees is only available if you selected Personal Address Book. If you don't select Enable searching for invitees, you will still be able to open your personal address book, but it will not be searched when locating people or adding attendees.
