Actually, the script seems to run all the steps, but just does not place the outgoing email into the Outbox. I am using Macintosh OS X ad Microsoft Entourage.
What version of Filemaker are you using?
If your script runs all the steps correctly, it must be doing something with the email. Does it send it and put a copy of it in the sent box? I'm puzzled why you are using Mac OS with a Microsoft email client. Why not use Mac Mail? Or, if you are using version 10, just send it using the SMTP option.
Tell us more.
Thanks for the ideas, however, I found everything works as it should if the Perform Without Dialog box is checked.
