Internal Address Book
Otherwise known as the LDAP (Lightweight Directory Access Protocol), the Internal
Address Book stores internal company addresses on the company network. The
System Administrator creates the Internal Address Book.
The display of the search results is defined by the LDAP. For example, the LDAP
server can return a search query "And" as "Andrew Smith" when the result
"Andrews, James" may have been expected. The lastname, firstname or firstname,
lastname display is controlled by the LDAP server and not your machine.
If you have successfully logged in via Authentication mode, your machine will
automatically attempt to match your login name to your e-mail address. Your name
will then be entered into the From e-mail address field. You will not be able to
change this.
