Outlook 2007 spell checker not working

Hi there,
I have issues with using outlook 2007. Outlook is not checking any words if i type it incorrectly. If i do spelling mistake, it wont show red underline under it. What is wrong? Can anyone help?

Thank you in advance.

Spell check is becoming more involved with all sorts of programs. It started out with Outlook and Word, but now there are spell checks for social marketing sites, Instant messengers. If your interested in any of these programs here: http://www.texttrust.com/

Try this:Go to Tools => Options => Spelling & Auto Correction => [Popular] Language Settings => Enabled & Primary editing language to English (United States)

Try to reinstall Outlook again. Deleting signature seems to have fixed it for me. Every time I create a signature it stops working. Just give a try.
