Exchange iCal can't save events

I was wondering if anyone has had a similar issue to this, and could suggest any resolution, as I've been banging my head against the wall for some time over it!!

I have set up a Microsoft Exchange Server Account with email, calendar and contacts all synced between Mail, iCal and Address book, however I am getting an error message that appears on screen in iCal every ten minutes or so saying that:

"iCal can't save the event "xxxxx" to the Exchange server. The account "xxxx" currently can't be modified. To discard your changes and continue using the version of your calendars that's on the server, click Revert to Server. To save your changes on your computer until the problem is resolved, click Go Offline."

It occurs even when I haven't been modifying the events and will continue to pop up throughout the day.

When I check the log file in Console, the errors look like this.

iCal[224]

error = Error Domain=CalExchangeErrorDomain Code=-4 UserInfo=0x115ce5400 "iCal can’t save the event “12.30pm: appt at clinic” to the Exchange server."

Does this seem familliar to anyone? Any help would be much apprieciated.

PS I have seen this feed: https://discussions.apple.com/thread/2140073 and have tried it, but with no luck!

Cheers.

FWIW I experience the exact same problem at my workplace when I turn on my coworkers' Outlook delegate calendars in Snow Leopard's iCal.

My workaround is to uncheck the checkboxes for these calendars in the Delegation tab of iCal's Account Preferences pane.

The drawback of this workaround is that my coworkers' calendars no longer are current. I need to reenable the above checkboxes to update the calendars.

This may come too late for you but I had this problem and for me it is an issue of having 2 machines (desktop + laptop) with iCal connected to the same exchange server. The problem goes away for me provided I remember to only have iCal open on one of my 2 machines.

I also have the same problem, but the curios thing is that it wasn't happening with Snow Leopard, and also with IOS 5, in another forums many people are comenting the same thing. But nobody until know has come with a solution.

I am having the exact same problem. OS X 10.8.1 and Exchange 2010 with all service packs installed. Exchange syncs perfectly with all iOS devices as well as OS X 10.7.x. Upon upgrading to 10.8 (and now 10.8.1), I continually get a message like "Calendar can’t save the event “xxxxxxx” to the Exchange server." After saying "revent to server", I receive the message stating "Invitees not recognized..."

Apple, do you expect to address these issues?

This is the console output:

9/8/12 1:01:54.109 PM CalendarAgent[34024]: [com.apple.calendar.store.log.exchange.queue] [error = Error Domain=CalExchangeErrorDomain Code=-4 "Calendar can’t save the event “Breakfast with Michael Zimbalist” to the Exchange server." UserInfo=0x7fcb233e9870 {NSLocalizedFailureReason=The account "Venrock" currently can’t be modified. To discard your changes and continue using the version of your calendars that’s on the server, click Revert to Server., CalFailedOperationKey=<CalExchangeUpdateCalendarItemOperation: 0x7fcb23298340>, NSLocalizedDescription=Calendar can’t save the event “Breakfast with Michael Zimbalist” to the Exchange server.}]

and

9/8/12 1:01:53.892 PM CalendarAgent[34024]: [com.apple.calendar.store.log.exchange.queue] [error = Error Domain=CalExchangeErrorDomain Code=-19 "“Breakfast with Michael Zimbalist” had invitees not recognized by the server." UserInfo=0x7fcb21ca7290 {NSLocalizedFailureReason=You entered an invitee that wasn’t recognized by the server., CalFailedOperationKey=<CalExchangeUpdateCalendarItemOperation: 0x7fcb25525940>, NSLocalizedDescription=“Breakfast with Michael Zimbalist” had invitees not recognized by the server.}]

Thanks,

I had an 'CalExchangeErrorDomain Code=-4' provoked by a modification of an event which I apperently could not modify.

At least, it was provoked by one event in my callendar and the errormessage indicated the event.

I used the Exchange 2010 webinterface to delete the event, restart iCal, click 'neglect' and 'back to server' a couple of times and voila, it all works again for me.
