I have recently upgraded from FP8.5 (pc version) to FP10 (mac version) I have scripts that send emails using my installed client which was outlook but is now Entourage, however now it no longer seems to work. Any ideas?

What do your scripts look like? Does it have an attachment perhaps? The Send Mail script shouldnt work any differently on Mac. It uses the default email client.

It just doesn't do anything at all. The script is using the "Send Mail" command. It does everything else in the script, it doesn't throw any errors, it just doesn't send the mail. Typically in my PC version it would open up the email and I could make any changes and then send, however on my mac it does nothing, it doesn't open an email, I checked to see if it is sending it and I don't see anything in my outbox either. I did some research on this and found that some users were complaining that it sends emails to their drafts folder, but it doesn't do that either.

The drafts folder is correct behaviour for Entourage.

Did you try to send an email MANUALLY?
