Question : Problem: Blackberry re-recieving email after reply from outlook

I am re-recieving an email on my blackberry after I have replied to it in outlook.

I have a blackberry bold, with an imap email account configured to retrieve email from an Exchange 2007 server. This is the only account configured and the device.

 I am using outlook 2007 on my work computer, there are no email rules setup to forward on emails after replies or anything.

Every email I recieve comes through on my blackberry and outlook fine. When I reply to an email in outlook, I recieve the original email on my blackberry again a few seconds after I replied in outlook.

It is occuring on two other blackberry devices in my company. One of which is running entourage on his mac, so its not isolated to outlook. Could it be an exchnage problem?

Thank you in advance.

Which details your problem. It appears that this is an Exchange problem, however the proposed fixed (rollup 5 for SP1) did not resolve the issue for those users with the problem. I would recommend you continue to monitor this thread on RIM's official forums.
