vbscript to create and send email to exchange server 2007

I have an access database that I need to be able to create and send an email from, and thru an exchange server 2007. The exchange server does not have CDO nor MAPI objects installed, and IT will not install. There must be some other protocol that comes with standard exchange server 2007 install that can be used? I do have Outlook 2007 setup and successfully send/receiving from it (which I thought used MAPI), but I want this code to be email client agnostic. (i.e. not have to have a email client installed). I have viewed the msdn http://msdn.microsoft.com/en-us/libr...EXCHG.80).aspx but don't know how to find the conn.provider that my installation is using, nor the correct sMailBoxURL. Can these be found from the outlook settings?

Not even sure this code will work because it implies the use of CDO when creating the object, and CDO is NOT installed.

Any help is greatly appreciated.
Thanks!
