In Depth Information
The Mailboxes section of this dialog box lets you add additional mailboxes that will be opened
along with your own default mailbox. This may be desirable if you own more than one mailbox on
the server or if you have been granted delegate permission (as explained later in this chapter) for
one or more other users’ mailboxes. To add a mailbox, click the Add button and type in the
The other options on this tab are
n Use Cached Exchange Mode: Cached Exchange Mode was explained earlier in this
chapter. You can turn this mode on or off here as well as in the Change E-mail Account
dialog box as described earlier.
n Download Shared Folders: Select this option if you want Outlook to automatically
download any shared folders. If this option is not selected, a shared folder will be
downloaded only when you open it.
n Download Public Folder Favorites: If this option is selected, Outlook will cache any
public folders you have added to Favorites under Public Folders. Be aware, however, that
this can slow down the synchronization process if these folders contain a lot of items and
are very active.
n Offline Folder File Settings: Click this button to verify the name and location of your
Offline Folders File (although it is rare that you will need to change either of these). You
can also compact the file to reduce its size — something that’s good to do once in a while.
Setting Security Properties
The Security tab, shown in Figure 28.8, displays these three options:
n Encrypt Data...: If this option is selected, data transmitted between Outlook and
Exchange is encrypted for greater security with a small speed penalty.
n Always Prompt for Logon Credentials: If this option is selected, Outlook will prompt
you for your username and password each time it tries to connect to the Exchange server.
If other people have access to your computer, you may want to select this option to
prevent them from accessing your mailbox.
n Logon Network Security: This option specifies the kind of authentication that Outlook
uses when connecting to Exchange. There are three options available: You can select
NTLM Password Authentication (NTLM stands for Windows NT LAN Manager) and
Kerberos Password Authentication to specify that Outlook should use that security
model. You can also select Negotiate Authentication (the default), which tells Outlook
to use whichever type of security the server is using. You rarely, if ever, need to change
