I'm not sure if this is a feature or a bug. I have Zimbra Desktop Alpha(whatever the most recent is) on MS Vista Enterprise. I recently changed my password too. I noticed in /opt/zimbra/log/mailbox.log on my mailstore that I had a bunch of authentication errors on my account from Zimbra Desktop. I thought that was odd, because I currently did not have the Zimbra Desktop app running. I ran Zimbra Desktop and removed my account settings(since I'm not using it much right now) and the errors are no longer in my log. Is Zimbra Desktop supposed to continue checking mail, even when the app isn't running?
