    Can anyone confirm if they are having this problem in the absence of delegates? I only have this problem on one exchange account, the one for which I have multiple delegates.

    I don't have delegates and I have the problem.

    I do have a similar problem. My calendar syncs but only old objects up unitl about 6-7 months ago. Does anyone have any idea what this could be? I also get a small notification next to my exchange calendar in the left frame of calendar but I can not make out why. Is ther anyony who can tell me where I can find the similar windows in calendar as I can get in mail with the connection information and activity reports?

  • Geof Corb Level 1 Level 1 (5 points)

    Still no resolution.  Like others, deleting and recreating the account does not make a difference.  In fact, behavior is exactly the same on two different Mountain Lion machines connecting to the same Exchange account.  And given that this had worked fine prior to the OS upgrade, on both machines, suggests to me that this is very clearly a Mountain Lion issue and not a Microsoft issue as some Apple folks seem to believe.

     

    I had a suspecion that reminders have something to do with the problem but I haven't quite pinpointed yet.

    It wasn't Mountain Lion that did it to me — started when we switched Exchange hosts this summer. Though maybe that just means Apple was already getting it wrong in Lion. I dunno.

     

    In any event, I'm not ready to let Microsoft off the hook as long as that monstrosity known as Outlook (Windows) is involved.

     

    Meanwhile, we've got two iPads and an iPhone connected to that same calendar and they don't have any problems. I still don't get why iOS has to use ActiveSync and the Mac doesn't, but maybe we'd be better off if it did…

     

    I dunno.

    "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."

     

    I have the same issue as most of the other posters.  Nothing I've tried has made a lasting difference. The same Outlook/Exchange account works perfectly with my iPhone. This has got to be a hint about waht the underlying problem is - or how to solve it.  Anybody have any new ideas?

  • Pascal_Sartoretti Level 1 Level 1 (0 points)

    Same issue here on OS X 10.8.2. Re-creating the Exchange account seemed to solve the problem, but it came back as before a few weeks later.

     

    The same account syncs perfectly from my iPhone, so I guess the issue is not on the Exchange side.

  • TobyParnell Level 1 Level 1 (0 points)

    Same problem for me here too. Does anyone from Apple read these posts? It would be good if you could tag someone from Apple like in a Facebook post to get their attention! Oi, APPLE, what have you got to say for yourselves about this?

    It would be nice to able to vote for bugs, so that Apple can prioritize their handling.

     

    I have a few open bugs that I can live with, but this one is VERY ANNOYING (sorry for shouting).

  • robert222 Level 1 Level 1 (0 points)

    It worked for about a month, but then reverted back. Disappointing to have this issue all the time.

  • Geof Corb Level 1 Level 1 (5 points)

    Well, we know Apple isn't listening.  Maybe it's time for us to build a petition on Change.org to get their attention and get this fixed.  There must be hundreds, if not thousands, of users afflicted by this problem.  There are plenty at the university that I work at alone...

  • G. Pasarescu Level 1 Level 1 (0 points)

    If we want Apple to pay attention and fix this, then let's all go to http://www.apple.com/feedback/macosx.html and file a bug report. And once you submit it, pass along the URL to all your friends who are also experiencing it. If enough of us do it, perhaps they will fix it sooner rather than later.

     

    I, for one, am extremely tired of it. I have been having the same error messages pop up since upgraded my mid-2007 iMac to Mountain Lion from Lion ("Calendar can't save the event ----- to the Exchange server."). If I remove the Calendar / Reminders portion of the account and then add it back, the problem seems to go away for a day or two. Then it inevitably returns. Furthermore, when the Calendar issues crop up, any Reminders I add will not sync up to the Exchange server either (which means they do not show up in my Tasks in Microsoft Outlook).

     

    Removing and re-adding the Calendar portion of my Exchange account should not be a long term solution to the problem.

     

    I was so fed up that I recently erased my main hard drive and installed an unadulterated (as in non-upgraded) version of Mountain Lion, hoping that this would somehow solve the problem. It didn't. After perhaps three days, the silly error message began popping up again whenever I opened Calendar and it tried to sync an event I recently created to the Exchange server.

     

    Now let's submit those bug reports and plead with Apple developers to do something about it!

  • KendallB Level 1 Level 1 (5 points)

    Yeah, good idea! I just submitted a bug report and linked back to this forum thread. This drives me nuts every day!!

  • G. Pasarescu Level 1 Level 1 (0 points)

    Here is the bug I submitted. Feel free to use whatever portions are applicable to your situation and submit away!

     

    Ever since I upgraded my mid-2007 iMac from Lion (OS X 10.7) to Mountain Lion (OS X 10.8), I have been plagued by the following error message:

     

    Calendar can't save the event "-----" to the Exchange server. The account "----" 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 can get the problem to go away temporarily (for a day or two) if I uncheck the Calendar / Reminders portion of my Exchange account in System Preferences --> Mail, Contacts, & Calendars, exit System Preferences, and then go back in and check it again. Unfortunately, after a day or two this error inevitably returns.

     

    Furthermore, about the time when the Calendar error pops up, any tasks I have recently added (or add from that time forward) in Reminders will not sync up to the Exchange server either. I know this because they will not show up on either my iPad, iPhone, or PC laptop running Windows 7 and Outlook 2010. However, I have no problems creating, editing and deleting tasks via my iPad, iPhone, or Outlook 2010 on my laptop and then seeing those changes on any of these devices. Only my iMac, which for some reason is not able to sync changes to the Exchange server, is unable to see these task changes, or make any task changes that can be seen by other devices.

     

    For that brief moment after I uncheck / check the Calendar / Reminders portion in System Preferences, I am able to create, edit, and delete events in the Calendar app and tasks in the Reminders app without any problems. It is like heaven when it works correctly!

     

    However, removing and re-adding the Calendar portion of my Exchange account should not be a long term solution to this problem.

     

    In order to rule out the possibility that this was due to old configuration files that somehow were corrupting the Calendar and Reminders apps in Mountain Lion, I recently booted into Recovery mode, erased my main hard drive, and installed a clean, unadulterated (as in non-upgraded) version of Mountain Lion. Unfortunately, this did not solve the problem. After perhaps three days, the "Calendar can't save the event..." error message began popping up again whenever I opened Calendar and it tried to sync an event I had recently created to the Exchange server.

     

    I would love to use Apple Mail, Contacts, Calendar, and Reminders on my Mac when working with Exchange data. I have no issues with Mail and Contacts. Unfortunately, this has not been the case with Calendar and Reminders.

     

    I know there are many others who are experiencing this problem. Will you please help us?

     

    Thank you very much! I appreciate any and all efforts made to solve this bug.
