Hi Arnold
You can keep the Web Service just to receive the request, analize the data, and if ok enter a record in a "todo" table. Then it will give an immediate answer, i,e "the mail will be sent shortly" or "missing data" in case of error etc...
You can then build an out-of-process com exe that just sits on that "todo" table, then runs the excel automation/mail sending stuff whenever it spots a new request in the table...
