I was using ShellExecute for group emailing then found out that it fails after about 30 addresses in the "To:" section. Is there a work around to this problem?

Next I tried the approach of creating an outlook application object. I haven't had any luck finding a help topic that describes the various properties of this approach. I need for the email to be displayed not sent to the outbox. Is there something I can state other than "objOutlookMsg.Send" to get the message to display rather than go to the outbox?
