Greetings all kindly Exchange gurus! ;-) I'm stumped, I have searched extensively online and cannot find the first thin about this issue. At my company we run several exchange servers that are able to be accessed through BES, Outlook and a running "Outlook Webmail" Portal. The issue is this, very occasionally (once every 1500 emails or so) when someone uses the web portal access to author and send an email (or indeed forward an existing email) the system will translate the outbound message to random Chinese characters upon send. If the same user forwards/resends the same message minutes later it will arrive without any problems. Has anyone any experience with this?
