We are running Exchange 2007 spk3 on Windows Server 2003 R2. We also employ a SOnicWall Email security 300 for spam/virus filtering. We have a handful of users running a mix of Blackberrys on BIS. Three of these users are complaining that emails are showing up either in Chinese or gibberish on their BB's but fine in Outlook. It usually happens when they receive a reply to an email previously sent. These three users are not using corporate email addresses but rather 3rd party email services such as hotmail. I cannot reproduce this issue on my own BB after adding a 3rd party email address. Has anyone ran into this issue before?
