Windows Mobile Replies to a ticket create a new ticket

Hello,
We are currently using SC+ Build 6007 and the email functionality is great as we have no one based in an office, it is all field people. Everyone has their email going to a Sprint PPC6700 phone with Windows Mobile 5. Whenever we reply to a ticket from the phones it instead creates a new ticket. This is very annoying as many times I can reply to a ticket while in a meeting or at lunch to simple requests or merely to advise the customer when I will be contacting them. I do not know where to even begin troubleshooting this as an email should be an email. The email enviroment is an Exchange 2003 SP2 / Activesync setup. Thanks in advance.
