Strange problem with a client here. He is using a hosted exchange account from me and has blackberry BIS Service.
The strange thing is whenever he sends a reply from within Outlook (whether using Outlook 2007 or OWA), the original email that he was replying to, reappears as a new email on his blackberry.
For example if he had a messagefrom me in his inbox. He replies to that message from within OWA. The original message (the one he is replying to) appears again on his blackberry.
Even if repies to the same message again, the message again appears again on his blackberry.
What on earth could be causing this?
