Use the Enable Outlook Anywhere Wizard to enable users to connect to their Exchange mailbox from the Internet. Outlook Anywhere eliminates the need for users in remote offices or mobile users to use a virtual private network (VPN) to connect to their Exchange servers.

External host name
  • Use this text box to type the external host name. Users will use this name to connect to the Exchange server by using Outlook Anywhere.

Basic authentication
  • Click this button to use Basic authentication.

  • Basic authentication sends the user name and password in clear text. It also requires that the user enter domain, user name, and password every time that the user connects to the Exchange server.

NTLM authentication
  • Click this button to use NTLM authentication.

  • By using NTLM authentication, the user's credentials are never sent over the network. Instead, the client computer and the server exchange hashed values of a user's credentials. NTLM can also use the current Microsoft Windows operating system logon information.

  • Even though it is more secure, NTLM may not work with firewalls that examine and modify traffic.

  • You can use an advanced firewall server such as Microsoft Internet Security and Acceleration (ISA) Server 2006 together with NTLM authentication for Outlook Anywhere.

Allow secure channel (SSL) offloading
  • Select this check box if you will be using a separate server to handle Secure Sockets Layer (SSL) encryption and decryption.

  • When you use SSL offloading, the firewall in front of the Exchange server that has the Client Access server role installed ends the SSL session and then establishes a new non-SSL session to the Exchange server.
