Hi:
I don't really know how SAS communicates with Outlook. I suspect that you do NOT have control over "outlook-y" things like signature, fonts, etc, etc. When I send a mail using the "simple" method, it gets sent from my computer as "plain text" -- which means no fonts, etc. This happens, even though I have my Outlook default set to HTML.
If I create the email -inside- Outlook, I get my signature when I start a new mail (if I have the Tools--> Options set to insert my signature.) But, if I create the mail with SAS, then my signature is not used.
The SAS Companion for your operating system may have more information. Otherwise, you may want to work with Tech Support. (And, keep in mind that it's possible that you can ONLY send the body of the email as plain text by default because of some configuration on your system. Your mail administrator may have done something to the mail server to prevent programs from sending HTML or XML messages.)
