Configuring Security Properties
The following settings on the Security tab of the Microsoft
Exchange dialog box, control whether
Outlook 2010 encrypts data between the client and the server and how
authentication is handled:
-
Encrypt Data Between Microsoft Outlook
And Microsoft Exchange This setting determines whether
Outlook 2010 uses encryption to secure transmission between your
system and the server. Select this check box to enable encryption
for greater security.
-
Always Prompt For Logon
Credentials Select this check box if you want Outlook
2010 to prompt you for your logon credentials each time it needs
to connect to the server. This is useful if you are concerned that
others who have access to your computer might be accessing your
mailbox.
-
Logon Network Security This
setting specifies the type of authentication to use when
connecting to Exchange Server. The Password Authentication option
causes Exchange Server to use Microsoft Windows NT LAN Manager
(NTLM) challenge/response to authenticate on the server using your
current logon account credentials. This is the standard
authentication mechanism in Windows NT domains. Kerberos Password
Authentication is the default authentication mechanism for
Microsoft Windows 2000 Server and later domains. You can choose
either of these or choose the Negotiate Authentication option to
have Outlook 2010 attempt both.
-
Insert Smart Card Use a smart
card to authenticate to Exchange Server.
Configuring Connection Properties
The Connection tab in the Microsoft Exchange dialog box,
allows you to specify how your computer connects to Exchange Server.
You can connect through the local area network (LAN), through dial-up
networking, or through a third-party dialer, such as the one included
with Internet Explorer. The LAN connection option applies if you're
connecting over a hard-wired connection—for example,
when your computer is connected to the same network as the server. You
should also use the LAN option if you connect to the server over a
shared dial-up connection hosted by another computer.
Click Connect Using My Phone Line to use an existing dial-up
networking connection or to create a new dial-up connection. Select
the desired connection in the drop-down list, and then click Properties if you need to modify the
dial-up connection. Click Add if you need to add a dial-up
connection.
If you want to connect to the Internet or your remote network
using the dialer included in Internet Explorer or a dialer included in
a third-party dial-up client, click Connect Using Internet Explorer's
Or A 3rd Party Dialer.
The Outlook Anywhere group of controls lets you configure
Outlook 2010 to connect to Exchange Server using HTTP. The capability
to use HTTP to connect to a remote computer running Exchange Server
provides an additional connection option for users of Outlook 2010 and
can drastically reduce administrative overhead. Administrators do not
need to provide virtual private network (VPN) access to the network or
configure VPN client software for users to access the computer running
Exchange Server from remote locations.
HTTP access also provides native access to the computer running
Exchange Server as an alternative to Outlook Web Access (OWA) for
users.
The Connect To Microsoft Exchange Using HTTP check box, if
selected, causes Outlook 2010 to connect to the computer running
Exchange Server using the HTTP protocol. To configure additional
settings, click Exchange Proxy Settings to open the Microsoft Exchange
Proxy Settings dialog box.
Configure settings in this dialog box using the following list
as a guide:
-
Use This URL To Connect To My Proxy
Server For Exchange This option specifies the Uniform
Resource Locator (URL) that serves as the access point for the
server. The default is <server>/RPC,
where <server> is the web address of
the front-end server running Exchange Server. An example is
httpmail.boyce.us/rpc. Omit the
https:// prefix.
-
Connect Using SSL Only Select
this check box to connect to the server using Secure Sockets Layer
(SSL). Note that Outlook 2010 changes the URL prefix to
https:// for the URL. (See the preceding
option.)
-
Only Connect To Proxy Servers That
Have This Principal Name In Their Certificate This option
specifies the principal name for the remote proxy server for SSL
authentication.
-
On Fast Networks, Connect Using HTTP
First, Then Connect Using TCP/IP With this setting, when
Outlook 2010 senses a fast connection to the server, it attempts HTTP first and
then resorts to TCP/IP if HTTP fails.
-
On Slow Networks, Connect Using HTTP
First, Then Connect Using TCP/IP With this setting, when
Outlook 2010 senses a slow connection to the server, it attempts HTTP first and
then resorts to TCP/IP if HTTP fails.
-
Use This Authentication When
Connecting To My Proxy Server For Exchange Select the
authentication method to use to authenticate on the remote
computer running Exchange Server. Choose the type of
authentication required by the front-end server.
Verifying Connection Status
After you have finished configuring Outlook 2010 to use RPC
over HTTP to connect to your computer running Exchange Server, you
can verify the type of connection that it is using. To do this, hold
down the Ctrl key, right-click the Outlook 2010 icon in the system
tray, and then choose Connection Status to open the Microsoft
Exchange Connection Status dialog box.
Testing AutoConfiguration
Outlook 2010 supports automatic account configuration, which
means that Outlook 2010 can attempt to determine your account
settings automatically. With Exchange Server 2010, Outlook 2010
relies on being able to identify and communicate with the
autodiscover host for your domain, such as
autodiscover.tailspintoys.com. This host
corresponds to a virtual server hosted on the computer running
Exchange Server. With versions of Exchange Server prior to 2007, you
must specify your name, email address, and account password, and
then Outlook 2010 attempts to identify the appropriate server based
on that information.
To be able to resolve the fully qualified autodiscover host
name, your client must be pointed to a DNS server that hosts the
records for the autodiscover host or that can forward a query to the
appropriate DNS server(s).
After your client is configured appropriately to resolve the
autodiscover host, you can use a feature in Outlook 2010 to test the
capability to discover account information. If you are having
difficulties viewing free/busy information or using the Out Of
Office Assistant, the inability of the client to contact the
autodiscover host could be the problem.
To test the connection, create an Outlook 2010 profile, with
or without a valid email account. To do this, start Outlook 2010,
hold down the Ctrl key, and right-click the Outlook 2010 icon in the
system tray. Choose Test E-Mail AutoConfiguration to open the Test
E-Mail AutoConfiguration dialog box.
Type the email address for your Exchange Server account in the
E-Mail Address field, type your email account password in the
Password field, and then click Test. If AutoConfigure succeeds. If
AutoConfigure fails, the dialog box will display an error message
indicating that it was unable to determine the correct settings. If
you receive the error, verify that the client is configured for the
appropriate DNS server(s) and retest.
