I have a basic zimbra installation. I only want to use this for calendar and contact sharing.
I also have an hosted exchange with users using outlook client.
I would like to setup zimbra so every management from zimbra i.e event created, deleted etc should sync to hosted exchange. (Note no plugin or software can be installed to exchange server)
Users currently using outlook calendar should be able enters event from their outlook view or owa view, it should sync to zimbra
Vice versa, When they also enter event from their zimbra view, it should sync to their outlook calendar
Ability for outlook users to subscribe to shared calendars on zimbra (do not want the shared calendar to be public - need it shared so users use credentials)
