You can do it using AppleScript. Open Script Editor
(HD/Applications/AppleScript/Script Editor), and paste this in:
-- Start Copying
property mysubject : "Whatever you want..."
tell application "Microsoft Entourage"
make new draft window with properties {subject:mysubject}
end tell
--Stop Copying
Change the "Whatever you want..." to the default subject you want, enclosed
by quotation marks.
Then, go to File -> Save As. Save it as a compiled script to HD/Users/<Your
User>/Documents/Microsoft User Data/Entourage Script Menu Items. I would
call it something like "New Message with Default Subject" or something like
that.
If you want to assign a keyboard shortcut to this, call it "New Message with
Default Subject\cmN". Then pressing Command-Shift-N will create a new
message with the subject already filled in. more information on assigning
keyboard shortcuts:

Then, in Entourage, when you want a new message with this subject, go to the
Script menu (next to Help) and select the "New Message with Default Subject"
script. A new message will show up with the subject already filled in.
