I'm having a problem with Calendar and Exchange syncing (my company uses Exchange 2010), with the following error:

 

"Calendar can’t save the event “Item title” to the Exchange server.

 

The account "Exchange" 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."

 

The options on the dialog box are:

 

Revert to Server

Try Again

Ignore

 

Syncing in general is working, i.e., items added in either system show up as they should. And, I'm not actually changing anything on the items on my MBA. The error pops up apparently randomly--so far, at least, I haven't been able to identify a pattern. I've checked credentials, which seem to be correct, and I've verified that time zone settings are turned on as I think they're supposed to be.

 

Any ideas?

    I have the same problem on two different Macs, both running Mountain Lion.  I did not have this problem on either machine prior to the upgrade.

     

    In my experience, these errors appear *after* the event has occurred.

    I also experianced this problem after an upgrade to Mountain Lion.

     

    I think it has to do with the fact that in Lion the account settings were managed from iCal, and now they are managed by the OS?

     

    Anyway I finally solved it by:

    • Open Calendar (formerly iCal).
    • Go to the Calendar menu and select Preferences.
    • Select the Accounts tab.
    • Remove the Exchange server account which is giving you the error messages.  This calendar will be removed from the Calendar app.
    • Go to System Preferences and click on the "Mail, Contacts & Calendars" pane, find your Exchange server account, and check the "Calendars & Reminders" option to re-enable your calendar.
    • Your Calendar should now sync properly.


    I had to do this for all of the accounts I had set up in Calander, and haven't had any problems since.

    Didn't work for me. I have deleted accounts, blown out keychain config, and just about everything else I can think of to try to remedy this.  Something is clearly not right.

    This didn't work for me either.  I completely removed my accounts and it came back.  It's happening on both of my Macs.

    I was hopeful this would be fixed in 10.8.1, but it's not.

    10.8.1 didn't fix it and this solution doesn't work unfortunately. This is a serious issue and I am shocked that Apple can't fix this. Can we escalate this? Who do we escalate to?
