Entourage - How to empty "Deleted Items" folder?

Another simple question. How do I empty the “Deleted Items” folder in Entourage? I can’t figure it out from the Entourage Dictionary. I tried


tell application "Microsoft Entourage"
    set deletedMessages to messages in deleted mail folder
    delete deletedMessages
end tell

but that doesn’t work.

TIA

Thanks, Jacques. That did it.

or you can use the entourage interface in schedules to delete on quite or delete on an interval.
