tell application "Microsoft Entourage"
make new draft window
set subject of window 1 to "hello"
end tell
“tell window” is usefull if you are going to do a lot of things with the window, (add email address, add message add attachment etc.) then it saves you “of window 1” on each line…
IMHO the try end try is only needed when you are not sure if it will work.
Like opening a file: you don’t know for sure if it is there; it might be deleted or moved.
In this case however:
You just created the mail window, so you are pretty darn sure it’s there, so try isn’t needed here.
