Sent Messages from Outlook on my blackberry

Hello everyone.

First time poster, so I am sorry if this is not in the correct spot, but I have been having a little issue that maybe someone has run into before.

I have the curve 8310 connected to a BES, everything is working great except sometimes when I send messages from Outlook 2007 I look on my blackberry and it has messages from me in my inbox only on the blackberry. I have show sent items to yes but sometimes it jsut does this.

Any ideas??

Thanks in advance.
