Sent Items Not Syncing.

[moe the great]

I have a user using Mac Mail + Zimbra iSync Connector and all appears to be fine.. except his Sent items are not staying on his laptop. They show up on the server but they are not in his sent items on his laptop. (this might not be a Zimbra issue but as I am new to both I thought I would ask here.)

Any Suggestions?

Thanks
