You will need to use the Microsoft Office Connectors. First review the documentation on the Excel Connector: http://help.openspan.com/80/Components/Microsoft_Excel.htm. Then review the outlook documentation: http://help.openspan.com/80/Components/How_to_use_the_Email_Component.h… and I will also point out that Outlook supports HTML bodies and it can be setup as described in this pdn post:

Then design your automation to pass the excel data as a html table to the body of the outlook email. It may be easier to format the data to a html table in a c# script.
