Update: my colleague has the same phone (but unrooted) and has the same problem. So it seems to be a real issue with the combination of HOX and Zimbra.
I also live by my calendar. Therefore, I found a workaround: get CalDAV-sync from Google Play. This works with Zimbra, and it you get the benefit that it is possible to sync more than one (default) Zimbra calendar.
I use CalDAV-sync (beta) now and it works as it should. The two-way sync is the beta part but it works without any error until now. I know it is a commercial app, but the price is low compared to the time lost in testing/debugging zimbra calendar with the activesync
I haven't tested lvsync.
I did test icssync, which is free, but I could not get this to work wit Zimbra.
