This feature requires you to be using a Microsoft Exchange Server 2003 e-mail account. If you do not know what version of Exchange server your e-mail account is using, contact your Exchange administrator.
These steps are for connecting Microsoft Outlook to your Exchange server without using a virtual private network (VPN) or other security hardware to connect behind your organization's firewall. Your Exchange administrator must enable this feature first before you can use it.
To specify a proxy server, click Exchange proxy settings.
Note If you use Basic Password Authentication or Password Authentication (NTLM) and an LM Compatibility Level less than 2, you will be prompted for a password each time a connection is made to the Exchange server. For more information on the LM Compatibility Level registry setting, see the Microsoft Knowledge Base for article number 147706. With Basic Password Authentication, the password is sent in clear text. For increased security, it is recommended that you use Password Authentication (NTLM), Connect with SSL only, and Mutually authenticate the session when connecting with SSL. In order to use mutual authentication, you must also specify the principal name of the server.
