ITunes stalls when syncing calendars to iPhone

My iPhone works wonderfully, except for one very big problem:
I plug my iPhone into my MacBook's USB port... I start iTunes, then click the checkbox next to the "Sync iCal Calendars" option. I choose "All Calendars," and then press "Apply."
The sync process begins, and then when it gets to "Syncing calendars...." it just sits there. I can let it sit for hours, and it will not move past this point.
Any one else have this problem? Is there a fix?

Every time it crashes, it adds to 'other' which is why I had to restore it to begin with.

  • ITunes could not sync calendars to iPhone because the iPhone disconnected

    error message
    iTunes could not sync calendars to iPhone because the iPhone disconnected
    I have spoken to Apple a couple of times in the last week (approx 2hr) apple support said it could be a Microsoft issue I have spoken to Microsoft and read endless information from the net and it seems that Microsoft is not the issue.
    I have uninstalled itunes and reinstalled, reset all settings in Settings\General on the phone, reset sync history on the iPhone, upgraded microsoft office 2003 to 2007 and I am still getting the error message.
    I have a iPhone 3G, pc is running windows 7 and just upgraded to microsoft office Home and Student 2007 and Office Outlook 2007.
    iTunes version 11.0.2.26
    iPhone iOS 6.1.3
    I have the same error on my wife's iPhone as well.
    Any help would be great.

    Thanks midwestcraft. I had this problem and your answer solved it for me.
    Thought this further info may be of use to some who wants more historic dates in their calendar.
    I had "do not sync events older than" unchecked and the input field set to "0". When I changed it to 180, it worked perfectly. I've found that I can increase this number to "545" - anything higher causes the error. This seems to coincide with some strange multiple-entry events in my calendar.
    Don't know if this will be a clue for somebody to fix the issue.

    One thing that might help.
    1. open itunes preferences from the edit menu and click on the devices tab.
    2. check the box to disable syncing for iphones connected to itunes and click ok.
    3. Then click the button to reset sync history.
    4. Now click ok to close the preferences window.
    5. connect the iphone to itunes and go to the info tab.
    6. scroll to the bottom of the info page and check the box to replace the ical data on the iphone.
    7. then click apply on the bottom right of itunes.
    This will overwrite any events on the iphone, including any events that has become corrupted.
    Hope this helps

  • TS1638 When syncing calendar on iPhone with Microsoft Office whole day appointments get moved to double day. I am aware this may be caused by conflicts in clock, viz daylight saving time. However, Outlook seems OK and takes time from Windows time and zone

    When syncing my iPhone to Microsoft Outloook all the full day appointments become two day - 2300hrs to 2300hrs next day. Sometimes this will include a nuber of a single day of 23 hours. Looked at solutions and all point to a clock issue or a daylight saving and winter times. Outlook operating time is directly from the Windows clock that incudes the change of times for daylight saving etc. It is set for UTC Dublin, Edinburgh, Lisban, London with daylight saving included in the options. I can't see what I can do.

  • ITunes crashes when syncing photos since iPhone upgraded to iOS 5

    Recently ran the iOS 5 upgrade on my 32GB iPhone 3GS, everything works fine on the phone (despite losing an app I'd paid £6.99 for - grrr!) but iTunes syncing isn't working properly.
    I can sync books, podcasts, music, ringtones all fine, but when it comes to photos, it just crashes as it tries to sync the first one. I tried restoring the phone, but now I just have no photos on it at all, and it still won't sync.
    I get the same issue on 4 different PCs, different versions of iTunes, different cables, so it has to be a problem with the phone? So annoying as I'd really like to have photos on the device, as as Apple make you use iTunes to sync them (why you can't just drag and drop them on there is a mystery to me) I'd quite like them to fix the problem they appear to have caused with their update.
    And yes, I can sync the photos fine to an iPod Classic, 3 different Nanos and an iPad 2.

    I had identical issue and just found the answer here -

  • ITunes crash when syncing apps to iPhone 4s

    I recently had to restore my phone as new.  I was able to sync to iTunes from my PC with no problem.   However, when I try to sync ANY apps, iTunes crashes.  How can I stop this from happening???

  • ITunes 8.1 won't sync calendars to iPhone for me

    I just installed iTunes 8.1(50) and am trying to synch my iPhone. It appears to synch everything except for calendars. After synching is completed, iTunes displays an alert saying: "iTunes could not sync calendars to iPhone 'Darrin's iPhone' because an error occurred while sending data from the iPhone." I have iPhone OS 2.2.1 installed. My console logs show this problem when the calendar sync fails:

    My problem - when syncing and error messages  comes up:  iTunes could not sync calendars to the iPhone because an error occurred while margin data."  I've tried turning the phone off and back on, & tried both USB ports but get the same thing.  What can I do next since it doesn't give me even one clue as to what the error would be?

    Before I started to resync calendars one by one as suggested in the troubleshooting article, I remembered something that came up in a sync when I first attempted :  a 'which one do you want to keep' message about a repeating calendar event, which came up with three options, one from Calendar, and two from iCal on the phone.  I deleted that event, then went through the calendar resync one by one, and all seems OK now.
    In Music there is a way to find 'ghost' items that show up as grayed-out on the menus, so that you can try to reassociate or delete them.  It would be nice to have a similar way to work with Calendar!
    Thanks for pointing me to the right article.

    hi there,
    i've found a great & simple solution for this problem
    just open your iCloud acc on iPhone
    turn off calendars (it wil ask you to keep info or not - KEEP IT!)
    and turn back on (MERGE!)
    now SYNC it..
    and that's it
    PS in my case it was contacts so the procedure is the same..
