Hi, I think you're talking about RPC over HTTP, if not, please let us know. A KB regarding How to configure RPC over HTTP in Exchange Server 2003 http://support.microsoft.com/kb/833401 After you deploy it, by default, you need to enter password every time, see the following thread to resolve logon automatically issue. http://social.technet.microsoft.com/forums/en-US/exchangesvrclients/thread/bc67310e-8133-4b77-be3b-380f0b0b4184 Thanks, Elvis

my main issue is when i try to send email using a vb code i have writtent from my exchange making it a smtp server, i do not have to give any password, which makes me think there is no SSL configured for this, when i connect my exhcnage from outlook 2007 its asks me for some authentication for the first time , does having RPC ssl over http solve what im trying to achive? because i want my excahnge to authentcaite using SSL each time a email is sent .

Hi, Whether you have to provide password is not related to encrypted communication. RPC over HTTP can achieve your goal have SSL authentication and also configure outside, but the mail client is Outlook, you are using a vb code, so it may not what you want. As you want to encrypt the smtp mail flow, you can refer to the following KB article: How to help secure SMTP client message delivery in Exchange 2003 http://support.microsoft.com/kb/823019/en-us Thanks, Elvis
