On the Tools menu, click E-mail Accounts or Account Settings, depending on your version of Outlook. To change the authentication mechanism on the Outlook client to NTLM, follow these steps: See the More Information section for additional details.

Many firewalls and proxy servers will prevent successful NLTM authentication, whereas Basic authentication will work successfully. Note: Before you switch to using NTLM authentication, you must verify with your administrator that NTLM authentication is permitted or even possible in your environment. The actual authentication between Outlook and your Exchange server always uses NTLM. The authentication mechanism that you configure in Outlook is used only for the HTTP session to your proxy server for Exchange. So, if you want to log on automatically, you must configure your Outlook profile to use NLTM authentication to your proxy server for Exchange.

There is no way for the client to submit your user name and password automatically. Sometimes, when creating the Outlook profile, the Proxy Authentication Settings in the Connection option of the Exchange profile will be set to Basic Authentication rather than NTL Authentication.īasic authentication requires that you continue to type your user account credentials anytime Outlook is re-opened.

If you are running on Windows XP, Windows 2003 or Windows Vista, it is possible to save your password in Outlook 2003/2007. However, if the machine is not a member of the domain, then it appears that some people have got it to save the password and some have not. It seems that if the machine is a member of the same domain as the Exchange server, the user should not have to authenticate again, and the entire authentication process should be completely transparent. However, in some cases you are constantly prompted to enter your Exchange account password each time you open Outlook 2003/2007. In Windows XP or Windows Vista, it is my experience that in most cases Outlook 2003/2007 only asks you for your password the first time you open it, but afterwards that password is stored locally and you are no longer prompted for it.

You can read more about it on my “ How can I configure RPC over HTTP/S on Exchange 2003 (single server scenario)?” and “ How can I configure Outlook 2003 to use RPC over HTTP/S?” articles (and elsewhere on the site). RPC over HTTP/S is a method for connecting your Outlook 2003/2007 client to the corporate Exchange Server 2003/2007 from the Internet or WAN, without the need to establish a VPN session to the corporate LAN and/or needing to open many ports on your corporate firewall.
