New Zimbra Desktop install on Zimbra 6.0.x server.

Large inbox, created a number of folders and subfolders in Zdesktop. Moved many inbox messages to folder.

It's been over an hour, and none of these new folders appear in the web interface.

How do I force ZDesktop's folders/changes back to the server? (I've tried send/receive, exit/restart with no change)

Thanks
