WEB MAIL using IE7

I am currently out on medical LOA so I am using IE7 web mail as a way of communication to the office.
When I do a reply to an email the test comes out in Japanese, Korean or something like that to the user I am replying. I have looked through all of my internet options but haven't found any settings that reference anything other the English. Can someone help me as this is driving me crazy.

Thank you Rick
