Out look Exp spell check

I can't get outlook Express to check the spelling of my Emails on my desk top. I have Windows XP home edition and MS office.
I have checked my MS-Word(Ver6)to make sure that it spells checks and it does the spell check of Word documents without any problem, also in Outlook Exp. -> Tools -> Options I have made sure that I have a check mark to for the spelling and correction Etc. but I can't seem to find out what my problem is. I also have re-installed both Word and Outlook Exp. on my Desk top.
Can any body tell me what I am doing wrong?
By the way the message I get just before I send out my Email is "the spell check on this document is halted do you still want to send it?"...
