Sending new calendar event to attendees?

Ok,

Maybe barking up a dead tree, but thought it was possible to send an calendar event to attendees using release 14.2 to Microsoft Outlook using OS X 10.7.

Got this so far, runs, makes an appointment (event) but with an attendee? But …

tell application “Microsoft Outlook”
activate
set theAccounts to the exchange accounts
set theAccount to the 1st item in theAccounts
set theStart to (current date) + 720
set theEnd to theStart + 1440

set em to {type:unresolved address, name:"Wizard", address:"wizard@xxx"}
set eR to {em}

set theEvent to (make new calendar event with properties {subject:"The Cauldron", start time:theStart, end time:theEnd} with attendee given email address:em)

How to invoke "send meeting theEvent" to actually ask them?

Anybody managed to do this? Find any documentation/examples? does seem to be a “send meeting” but ?!?

Thanks
