Issue Description: There is an issue with Chrome browser where a Zero Width Space () character is sometimes prefixed to the body of the email that has been composed via OWA, in Chrome. When the email is then sent, the recipient sees the Zero Width Space displayed as a “?” in the email.
Latest Update and Guidance: This occurs only while using the Chrome browser which is being investigated by Chromium under the bug 578155. The workaround is to access OWA via browsers other than Chrome such as Internet Explorer or Firefox if this is seen to be causing an issue for end users.
