I have to write a VBScript which will run on a Windows Server 03 (no Office, SMTP, etc. installed - like it's a fresh installation). This script should send E-Mails over an MS Exchange Server (on another server). So now I have a meeting with the head of the team managing those Servers. To prepare I'd like to know **what ways I have to send an E-Mail from a VBScript over an MS Exchange (also including how to authenticate with the Exchange Server)?**

As far as my googling goes there is one way with CDO (only SMTP?) which can use the current user for authentication or a clear text username & password.

*edit:*
Or am I mistaking and there is only SMTP for sending E-Mails over Exchange Server? Also that there is only authentication with clear text / using current credentials?

Cheers,
Gregor
