    I've been struggling with this for a while.

     

    In my case it predates Mountain Lion — started when we moved to Rackspace in June.

     

    Only certain events trigger the error message. One in particular is a weekly repeating event, so I'm scrutinizing it for clues.

     

    So far all I can see is that it was marked "Free" instead of "Busy." I'll change that and see what happens (or doesn't as the case may be).

     

    For what it's worth, I've tried adding the Exchange calendar directly and indirectly (using delegation through another account). Doesn't seem to make a difference.

    I found some posts on other sites that say the problem relates to time zone support, but when I try those solutions of toggling the time zone support I still have the error.  +1 people having this problem.

    Still getting this in 10.8.2.

  • MattTurner Level 1 Level 1 (0 points)

    +1 -- only happened after upgrade to Mountain Lion. Have tried the time zone support, deleting all Exchange accounts in Calendar, Mail, Notes and Contacts, and then adding again through the system prefs. It'll work for about a day or two, and then the problem returns. Events show up just fine on the iPad and iPhone, but problems with iCal.

     

    I have Outlook for Mac 2011 on my machine and no sync problems. But I hate being forced to use it.

     

    I'm using 10.8.1.

    I have been having these issues since 10.7.  I just recently got a new MacBook Pro Retina.  I did NOT migrate my data, because I wanted to see if we were still seeing these issues.  So from a fresh install, I connected Callendar.app to my Exchange 2010 + SP1 environment (no rollup updates or anything other than SP1).  I still get the same thing:

     

    - Calendar can't save the  event "<event name here>" to the Exchange server.

    - The account "<calendar name here>" 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.

     

    I called apple support and was immediately "transfered" to microsoft support.  But in reality, they simply transfered me to Microsoft Professional Servers so that I can could pay $500+ to have them look into my Exchange Server.

     

    I called back and spoke to another person at Apple.  They informed me that they don't "support" servers.  I explained to them that this is not an Exchange Server issue, but rather a "Calendar.app" issue.  This is a read-only calendar that I am connecting to as a delegate.  The Calendar.app should NOT be trying to "save an event to the exchange server."

     

    This was terrible support from Apple... I hope they fix this issue.

    I know that on mine, another issue that crops up is that Calendar seems to erroneously attempt to turn an appointment into a meeting with invites. I can see this when I open the events in Outlook on my Windows machine: right after an appointment time passes, I get an error and then I can look at the meeting in Outlook and see that the "Invites" field is now active but empty. This ONLY happens when I'm connected to Exchange on my MBA.

     

    Perhaps the error is related to Calendar trying to change the meeting type, and you might get it on yours all the time because it's a read-only calendar. That doesn't explain why I get the same error where I have rights to change the events, but...

  • Sorry Comforter Level 1 Level 1 (0 points)

    Similar problems started appearing for me weeks after installing 10.8.2, suggesting another triggering cause. I have tried various fixes suggested in this and other threads, with no success. Besides treating meetings as invites I get multiple invitations for every appointment in my calendar - sometimes as many as a dozen sent to my email account.

  • Hyde Level 1 Level 1 (0 points)

    same problem here. tried different solutions. works fine in outlook but it's a major problem in calendar, especially for people with a lot of delegates.

  • MarkAldred Level 1 Level 1 (0 points)

    It has happened to me too. Macbook air. Synced with exchange calender for a year but stopped syncing in about Sept 2012. I phone still syncs fine.

  • jaydeejd Level 1 Level 1 (5 points)

    I am still having this issue with both my MBA and my Mac Pro, both running 10.8.2.

    No problems with calendar syncing on my iPhone or iPad.

    Anyone know if Apple is trying to address this major headache?

  • hootjr Level 1 Level 1 (0 points)

    I don't know of any current support issues opened with Apple.  My issue was resolved by deleting the Exchange meeting and resetting it up to only repeat for 6 months.  So maybe Calendar.app has a bug in that it can't sync past 6 months or so?

     

    The other issue that I am having now with Calendar on 10.8.2 is that CalendarAgent is consuming all my memory.  This laptop has 16G of ram.  It seems to be the case that when I close my laptop for the evening, CalendarAgent starts consuming both cpu and memory resources.  I just opened it this morning and read your message about this Exchange Sync issue and noticed that I was 11G into swap!  The workaround is simply to Force Quit the CalendarAgent and then swap returns to a reasonable 1-2G (my real memory goes down tremendously too). 

     

    I need to open an issue on that CalendarAgent issue, but just haven't had time.  When I called Apple regarding the Exchange sync issue, they told me to hold and forwarded me to MS support

    hootjr:

     

    1. My calendar issues occur both with recurring events and single events, so I don't think it is a recurrence issue.  I have many calendar items in one Exchange account and I get sync issues almost daily.  The only solution has been to delete the account and re-create it.  (That is until I moved all my calendar entries to Gmail.)
    2. I don't think CalendarAgent consuming even 1 GB is normal.  It should be well under 100mb.  I have experienced CalendarAgent eating memory a couple of times, but if it stays in the 1GB range for you that is probably not right.

     

    I also experience many weird issues with Mail and Exchange, including failure to sync new messages, failure to move messages, Mail hanging for extended periods of time, etc.

     

    I agree that Apple likely doesn't troll these forums.  We either have to live with the pain, switch email systems, or switch email clients.  Or we could orangize the 100 Person March on Cupertino...

  • MarkAldred Level 1 Level 1 (0 points)

    Agreed. I fixed mine but only by deleting the account and then re creating it. Once re created it syncs straight away. It is working properly.....for now. It doesn't take long. Certainly quicker than fiddling around trying different fixes.!!

  • KendallB Level 1 Level 1 (5 points)

    I have been seeing the same problem and also tried all the fixes, including deleting my calendar settings and setting them up again. That does fix it, or a short period of time. I also deleted the specific events causing the problem in question and recreated them, and that also fixes it. For a short period of time.

     

    All the events I am having this problem with are actually on my wife's shared calendar (it does not do it with my events on my calendar), but she has the same problem with events on my calendar she shares with me. And like someone else mentioned, the problem appears to be related to events with no end date in sight. My wife sets up lots of those of things she does regularly so they go into the future forever (until she changes them or decides not to do them), and it is only those events that seem to be having the problems, at least right now.

     

    I sure hope there is a fix for this as it is extremely annoying!

  • jaydeejd Level 1 Level 1 (5 points)

    This fix remains only temporary for me. Seems to last longer on my MBA than on my Mac Pro--I have no idea why as they are both running 10.8.2 and have identical account configurations. So frustrating.
