Spelling check Live Mail

I just replaced my OS from Vista to Windows 7.
Live mail offers spelling check for a number of language.
I have activated English, Spanish and Dutch with Spanish as Standard.
I assume that the language in Use is automatically recognized.
However it does not seem to be working that way because every word is corrected and many of the words recommended are not correct words.

I'm afraud not.
Open the options (from the small icon over top left)
Select Mail
Select the spelling tab,
You must click your principal language, and select it as deafault.
