Could not sync calendars to the "  " iPhone because an error occurred...

This error message pops up every time I attempt to sync iCal with the iPhone using the "merge" option. Replacing the calendar works but wipes out the calendar entries that are synced from my work Outlook calendar.
Now the "merge" function seems to work fine on my work PC but NO GO on the mighty Mac.
Yes all the software has been updated.
Need suggestions please.

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..

  • ITunes could not sync contacts to the iPhone because an error occurred

    When I connect my iPhone to my iMac (OSX version 10.6.6), and open iTunes and select "sync" - everything syncs (my Apps, Music, Movies, TV Shows, Podcasts, books, Photos and Calendars). However, I get an error message popping up saying: "iTunes could not sync contacts to the iPhone because an error occurred while merging data".
    I have unchecked the contacts button in iTunes and then sync works fine.
    I have deleted all my contact in my Address Book on my iMac and tried to sync. Again, same error message as above.
    I have not tried to restore the iPhone as I am worried to loose my contacts saved on my iPhone.
    Who know how to solve this problem? Thanks

    Hi Charlotte
    I had the same problem for one year now and it affected my contacts, then later my calendar.
    I followed the Apple troubleshooting guides and finally managed to make it work again.
    First try the following guide:
    iPhone, iPad, iPod touch: Troubleshooting contact and calendar syncing via USB on Window
    http://support.apple.com/kb/HT1692
    For me I noticed that after I updated ITunes to latest version (using the full uninstall from the last point of the guide above, section "Reinstall Apple Mobile Device Support and iTunes"), I could sync with another Windows user account (on another computer actually)
    Since I wanted my own account to sync again, I then used the advanced troubleshooting guide:
    Advanced troubleshooting for Sync Services on Windows with Microsoft Outlook 2003, Outlook 2007, or Outlook 2010
    http://support.apple.com/kb/TS2776
    In my case the point 4 in this guide helped, but since I had no MobileMe, I just killed the OS process SyncServer.exe, then renamed the SyncServices folder to SyncServices.old and restarted the PC.
    You should try all the steps in both guides in the order mentioned, to see which one can help, I don't advise you to start directly with a step in a guide
    Good luck

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

    Just went to sync my iphone today and got this message:
    iTunes could not sync calendars to the iphone because the iphone disconnected.
    Any ideas what the problem might be.  Had not had this happen to me before.
    Can't be iCloud because the only thing I use that for is Find My Mac.
    Restarted iTunes as well - still get the warning notice.
    Any ideas?

    I have the same issue - it just started happening.  Any suggestions out there??

  • I am getting a sync error between iphone and Outlook 2007:   ITunes could not sync calendars to the iphone because the sync server failed to sync the iphone.  How can I fix this?

    I have the "sync calendars" checked. 
    This happens about every three months and drives me crazy!
    I have a 2G iphone on T-Mobile.

    i use outlook for my work email, but my personal email is in gmail.  besides work email, i do not use outlook at all.
    i get my work email on my iPhone, but i do not sync calendars and contacts as i have to use an imap connection for work, and this does not allow for calendar or contact syncing.
    i have seen a gmail/outlook sync tool, but i am afraid i do not use it so i can not offer any help with it.

  • Itunes could not sync ^0 to the iphone because unknown error (-19) ??? help

    This is the error message i get when i try to install the update. Says it right after it starts to back up the phone. Thanks for any help

    I am getting the same error. My iPhone has been locking up for the past 2 days. I thought it was because I hadn't updated in about a month. I updated tonight and that didn't resolve the problem. It still locked up on me. I was going to reset to factory settings, but when I try to backup it locks up and gives me this same error message. Ahhh!

  • "iTunes could not sync calendars to the iPhone "ABC" because the iPhone disconnected"

    Hi.
    So, I have an iPhone 4 running iOS 4.3.5. I am syncing it using iTunes version 10.4.1 running on a MacBookPro running Mac OSX 10.7.1.
    When I do a sync it runs through the usual steps, including the step where it says it is syncing calendars, and each step appears to complete in the iTunes window. However, as it finishes, a warning message appears saying "iTunes could not sync calendars to the iPhone "ABC" because the iPhone disconnected". Here's a screen grab of the error message:-
    Now, the phone has not physically disconnected. I'm a bit baffled by this. It is a new iPhone 4, but inital syncs were performed without any difficulty. I have tried inserting a TEST event, to make sure that there is in fact a difficulty with the sync, and I can confirm that the error is not a phantom; syncs are not taking place. In additon, I have tried (albeit not methodically) to vary the particular calendars that are to sync, and the sync settings around old events, but to no avail.
    Any suggestions for trouble shooting this would be gratefully received.
    Thanks.

    Itunes could not sync calendars to the iPhone "TheButler's Phone" because the sync server failed to sync the iPhone, anyone?

  • "iTunes could not sync calendars to the iPhone "name" because the sync server failed to sync the iPhone".

    I get the message "iTunes could not sync calendars to the iPhone "name" because the sync server failed to sync the iPhone" every time I sync the iPhone 3GS with iTunes by USB.  Can anyone help? Please !!!!

    I posted the following to "iTunes could not sync calendars to the iPhone "xx" because the sync server failed to sync the iPhone. What does this mean??" at https://discussions.apple.com/message/15820680#15820680
    I haven't seen it mentioned but the secret is to
    Sync only selected calendars
    Select "Remove Calendars" from the popup window
    (This is ambigous: from where are the calendars removed?  From the device being synced to)
    Click apply.
    Oops!  My memory is already gone stale.  I think I left no calendars selected, then clicked apply.  Then I selected the calendars that I wanted, then clicked apply.
    In any case, I had a blank calendar on my iPad and then I had all the updated events that I wanted on my iPad.
    Thanks to all who provided some of the essential clues to resolving this problem.
