I had the same problem with one of my IMAP accounts (Cyrus IMAP 2.3.14). Here's a solution that works fine for me using Zimbra Desktop 7.1.4 GA (Build 11299).
When I wanted to write down a small HOWTO, I found this had happened in another thread already. See How can I sync "inbox/sent"folder rather than sent folder
To add, in a Windows 64 bit installation, the datasource.xml is located both at
So, if Zimbra Desktop is used by more than one user on the machine, you will maybe want to patch the user-specific datasource.xml only.
Here are my settings for the IMAP server mentioned in the beginning:
However, note that Drafts is not syncing, which is a known bug: Bug 46200 - Sync Drafts folder for known IMAP services
<service name="<MYMAILSERVERDOMAIN>" saveToSent="true">
<folder remotePath="INBOX" localPath="/Inbox" sync="true"/>
<folder remotePath="Drafts" localPath="/Drafts" sync="true"/>
<folder remotePath="Junk" localPath="/Junk" sync="true"/>
<folder remotePath="Trash" localPath="/Trash" sync="true"/>
<folder remotePath="sent-mail" localPath="/Sent" sync="true"/>
