I am able to work with chrome and firefox. The issue is only with IE8. If i work in ie 8 light mode , iu a able to compose mails and rpely to mails. Otherwise, when I click on New Message or reply to a mail , a new screen will come with the contents blank.
Try disabling all add-ons for IE and see if that helps. Has the security settings or any other configurations been changed on IE? Also can you verify if this is an issue with all IE8 on different computers or is it just the one you are testing with?
