Those users are now instructed to keep shared calendars open in the web client and to use Outlook for mail and personal calendaring.
(Of course, you may ask "Why do they need to have a zillion calendars open at the same time?" Usually, it's a power user in charge of juggling to few conference rooms.)
A possible enhancement for Zimbra would be to only sync calendars when Outlook has the calendar in a view...

some of the performance problems that you are seeing might have nothing to do with ZCO syncing but just normal Outlook behaviour. there is a memory overhead with mounting a PST to an existing Outlook profile. we were seeing this at around 15-20MB per mounted PST (shared calendar). so if you are mounting 40 shared calendars, you could be talking about an outlook process in the neighborhood of 800MB which could be killing performance and could make it seem like outlook is always syncing. I'm assuming that you are using Outlook 2003...this memory problem seems much smaller with Outlook 2007.
