You live in Oz, your Word dictionary is set up with English(Australian), (I didn't know there was that much difference between English(UK) and English(Autralian)), as default.
So, what do you want to set it to? English(US)?
What happens when you try to change it? Any error messages?
Did you follow the steps stated in this article?
Try as I can, I am unable to change the default language for the MS OUTLOOK 2003 spell checker.
WORD is the default e-mail editor for OUTLOOK and my WORD normal.dot has English(Australia) as my default language.
I do not want to move to the US so that my e-mail spelling is correct so your advice would be very welcome.
