Outlook 2011 reply to all and add text to the message

Hi all,

I am having a problem with adding text to a reply to all message.

I can reply to all using the code:

tell application "Microsoft Outlook" to reply to selection with reply to all

However I can’t work out how to add text to the message. I have tried to define the content: with what I require but that does not seem to work.

Any ideas please?
