We recently setup a new BES server with the Zimbra connector and seem to be running into one slight issue with the calendar.
Events created on the device show up in zimbra just fine. However, modifications to events made on the device do not. For example if I create an event called "Conference Call" on my device, then change it to "Meet in A building" my calendar in Zimbra will show the event, but it will stay as "Conference Call".
Oddly, if I stop services and open Outlook (on the BES Server) then the event is renamed properly. But it stays with the original "Conference Call" name for the end user. I'm giving it atleast 15 minutes for any updates to take place, it just never happens. This applies to Outlook on the users desktop as well as when viewing the calendar in the web interface.
Any help appreciated.
