Q: Calendar - Exchange sync issue

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?

    Well, it's been 4hours straight, added tasks, accepted meetings and yet no pop up :) let's see how it goes tomorrow.

    Not working for me. What I did was applying the update, restart, remove and add the Exchange account in Calendar. Same problem as before... GPUOD (the gray pop-up of death)....

    8-andrew-8, et al:

     

    I updated my machine with 10.8.4 and received the same error as before; however, once I a) removed the Exchange account in Calendar preferences; b) closed the program; c) opened System Preferences and checked Calenders / Reminders in the Exchange Account under the Mail, Contacts, & Calendars setting; and d) opened Calendar and put in my Exchange password, I have had no problems since.

     

    I am currently on Day 2 of this experiment. I just home from work, opened Calendar (it had been completely closed), and have not seen the dreaded bug pop up yet. I'll let you know if the bug comes back. I'm hoping it doesn't!

    Update: Just moved an appt. I had created in Outlook 2013 on a PC to another date; closed and reopened Calendar. No GPUODs. All good so far!

    48 hours and running without any pop-ups here.

     

    I did the following:

    1. Removed my outlook accounts from both of my macs through system prefs.

    2. Updated to OS 10.8.4

    3. Added the accounts back.

     

    I have added new appts and so have my delegates. Keeping my finger crossesd.

    Thank you, Apple.

    My calender seems to work again. What i did was to open finder and go to User/Library/calendars and delete the folder with .exchange in the end. I did also delete the Calendar Cache file. Before this I did shut down the calender. And then I re-opened the calender and it took around 5 minutes for the updating.

    Simply upgrading to 10.8.4 did not solve this issue for me (and I am not ready to one more time delete and recreate my account).

     

    It would be nice if somebody with access to the 10.9 beta could report on this. No need to break any NDA, just tell us if a few months of patience will solve this bug :-)

    So far for me, doing the delete and recreate appears to fix it. I finally did it on my MBA today, but it has worked on my MacPro and MacBookPro so far. Crossing my fingers ...

    Since the update, and for the very first time, I'm not having any Exchange synch prolems.  In the past within hours it would deteriorate.  Its now been over a week and still working fine.

    Delete the account and set it up again, more chance of success than trying to persuade people to break the terms of the NDA.

    After upgrading to 10.8.4 the day it came out and deleting/re-adding my Exchange account the problem is gone for me on both of my Macs...so far.  After upgrading to 10.8.4 I didn't delete/re-add for a while and still saw the issue.  It only went away after deleting/re-adding the Exchange account.

    My results have been mixed.  I never removed my Exchange email account, but I re-added the calendar.  I've gotten the Pop up of Death a few times, but when I click Retry it actually seems to work and the pop up doesn't come back.  I had migrated to Google Calendar so I don't have any old entries on my Exchange and I've only recently added a few entries on my Exchange calendar.  But from my limited experience so far it does seem to be working.  I have time zone turned on and settings much like others in this thread.  I'm curious to know if anyone else is getting the Pop Up and seeing it work when they click on Retry.

    Well,

     

    Last weekend I did a fresh install of my system with 10.8.4. Then added my Exchange account and...

     

    Sadly GPUOD came back after a while.

     

    It is weird, because I've found out the following:

    -Not using Timezone support always throws GPUODs

    -Timezone Support active but with Mexico City and any other from Mexico throws GPUODs

    -Tried using Central Time using Houston, Dallas and other US cities,works for a while then GPUOD is back after some cycles.

     

    On the last option I even reached a day working fine, but next day comes with a GPUOD since opening and never got to get it quite good since then. Sometimes it works sometimes don't.

     

    No workaround so far.

    Well, after digging a bit more I found out DavMail in SourceForge which is now doing the job with or without TimeZone support, cleaning cache, recreating accounts or whatever other trick.

     

    Basically you need to:

    1. Download DavMain from Sourceforge http://davmail.sourceforge.net/download.html

    2. Temporary "Allow applications downladedf from: Anywhere" on System Preferences - Security & Privacy

    3. Install DavMail.

    4. Reset "Allow applications downloaded from:" to either "Mac App Store" or "Mac App Store or identified developers.

    5. Run DavMail

    6. Leave Exchange Protocol to "Auto" and write your OWA URL (like https://email.server.com/owa/) or EWS (https://email.server.com/ews/exchange.asmx)

    7. Uncheck any protocol you won't use (I only left CalDAV HTTPS enabled) note port number (1080 in my case)

    8. Remove your Exchange Calendars

    9. Add new CalDAV using: your Exchange credentials (using DOMAIN\username form), and using http://localhost:1080 as CalDAV server.

    10. DONE! Although a bit slow, I am now Sync'ing with Exchange and iPad/BlackBerry/Outlook are receiving push notifications

     

    This has been the best bet I've found until Mavericks arrive. Lets hope this get fixed then.

     

    Find more info on CalDAV under http://davmail.sourceforge.net/gettingstarted.html

     

    Regards all!!!
