Syncing calendar doesn't complete

by synchronizing the calendar of my iPhone I got following (error) information:
+iTunes konnte Kalender nicht auf das iPhone XXXX synchronisieren, da bei der Neuzuordnung der Eintragsidentifizierungen ein Fehler aufgetreten ist.+
+versuchen sie ihr iPhone später erneut zu synchronisieren. wenn das Problem weiterhin besteht, ersetzen sie Kalender auf Ihrem iPhone im bereich Infos in den iPhone-Einstellungen+
I really don't understand the last sentence. what should I do to solve the problem?

Sigh No joy. I deleted the cache files, I even delete a lot of unused calendars and rename the remaining 2. logged out and logged back in. No only does iTunes not see them, but even if I select "Sync all calendars" Since I only have two and need both, I thought to skip the selection process and just do them all. Sync runs briefly, but the calendars on my iPhone are unchanged and I have no way to delete the ones that are there...

Addresses sync, Calendar doesn't. iphone-icloud

I am traveling, and using both a Mac laptop and an iPhone.
Entering a change in the Address book on either the iPhone or in iCloud via my laptop browser result in almost instant synchronization between the iPhone and iCloud.
I entered new events on my iPhone calendar, and they don't show up in iCloud. I enter a new event in iCloud, and it doesn't go to the iPhone.
In my iPhone settings:
Mail,Contacts,Calendar
iCloud
All sliders are set to ON
Does anyone have any ideas about what is going on here or what to do about it?
Thanks,
Phil

After iOS6 update, iPhone 4 doesn't sync calendar with iTunes

Hello,
I have an iPhone 4. After update to iOS6 the sync of my calendar has a strange behavior! It doesn't sync anymore. When I enter a calendar entry on iPhone, it's not synchronized with the macbook Calendar.
I changed calendar dates on my macbook - it won't appear on my iPhone4.
I badly missed some dates, till I found that the Calendar doesn't sync.
I also set in iTunes the marked, that on next sync the calendar should be replaced - but even then the new entries doesn't appear. Completely strange is, that if I delete the calendar on my iPhone and resync by iTunes, I get the calendar back, but the new or changes entries don't appear.
What can I do, instead of waiting to get my new iPhone5?

Now I have my new iPhone5...
And what should I tell you?dar. Neither from iPhone
There is still no sync of the calender from iPhone to MacBookPro and no sync of calendar entries from the MacBookPro to iPhone.
I am helpless. I tried to replace the calendar - it syncs, but the edited entries do not appear - they were sync with the old entries. Where the **** do they come from?
Normal Sync, nothing happens...what's a smartphone
Does nobody have a guess or anything I can try? Really, this *****... what's a smartphone without a syncronized and working calendar??

IPad Calendar doesn't sync back to iCloud nor Mac

Hello all,
I have a strange issue that, since a few days, the iPad-based, iCloud-linked calendar doesn't sync back to iCloud. Hence, for that reason, the calendar on the Mac isn't in sync, and this is, as you can guess, pretty annoying. iPad runs iPhone OS 6.1, and the Mac runs Snow Leopard. I manually configured the calendar portion of iCloud as indicated, and sync between iCal (Mac) and iCloud doesn't suffer any delay.
Additional information: when initially reinstalled, the iPad has two sets of calendars: one locally synced with the Mac, the other being iCloud, and there's overlap between the two, thanks to this pesky sync problem. I really appreciate the convenience of iCloud, but can't go without the safety of local sync. I may go days without manually syncing the iPad with iTunes but still, iCal is my lifeline, and any defect in keeping updated or worse, losing events will result in serious profesional consequences. It already happened in the days before iCloud.
iCloud-related information: my Apple ID is an email that has been dead for years. Since I used it heavily before the mailing privider ceased activities, I couldn't practically restart from scratch, so I am currently using this "fossil" login along with an updated Yahoo contact adress, and recently added an @me.com adress from iCloud. The latter is the adress is the one used to connect to iCloud's calendar from iCal, and works nicely.
However, the iPad, despite being configured with iCloud natively, doesn't update. I restarted it, but since the most up-to-date calendar is on the iPad and un-synced, so far I didn't try deleting and re-adding iCloud to the iPad as it would delete events added since.
What could cause the iPad to lose sync with iCloud, and how to solve that and prevent it from happening again?

David, nice to hear from you again, hope you are well.
This user tip might help you understand how accounts work with Address Book.
I believe you have duplicates because you have two sets of contacts. "iCloud" and "On My Mac". Once you have created all your contacts in the iCloud account, you should delete them from On My Mac.
You can move contacts simply by dragging and dropping from one account to the other, you don't need to export them all to the desktop (although doind so will serve as a good back up if all goes wrong). You should note that this copies them though rather than simply move them, so you'll need to delete the old set when you are done.
As for preserving groups from the On My Mac Account, you can't but you can simplify recreating them by copying contacts (drag and drop) from an on my mac group to an empty group in iCloud.
Not sure about the contacts that you are struggling to move.
Many aspects of iCloud are difficult to understand, have a mull through what I've said so far and come back if everything still doesn't fall into place.

Mobile account doesn't complete initial creation and sync process

I'm trying to setup a mobile account for a network account but it won't complete the sync process on the client MacBook Pro. Both the server and the MacBook Pro are running 10.5.5.
When I login to client it prompts me to create a Mobile account and proceeds with the sync to create the account, but when the sync is complete it just logs in with the default account setup. None of the user files or settings (desktop image, preferences, etc) appear. The sync process says "Checking..." for all the files that supposedly get copied to the client, but it looks like it doesn't complete.
Is there a way of knowing what the problem is? Is there an issue with the user's home directory, some file that prevents the sync and mobile home creation from completing?
Thanks.

I solved this myself. The user ended up have a folder on his desktop that contained a backup home folder from an old powerbook that he was trying to save. It was a complete home folder, Documents, Library, etc and I thought it might be interfering with the sync of the normal home folder. So I created a folder called Bad Stuff in the home folder and copied the old powerbook home folder into it. Then opened up the Sync Settings and excluded the Bad Stuff folder from the sync. And it worked, the sync when fine and is resyncing fine.
Hope that helps with other people with a similar problem.

Have you updated your itunes to the latest version? You have to have itunes to sync the phone to any computer.

IPhone 3G doesn't sync calendars and contacts via mobileme

Hi.
Since the initial setup, my new iPhone 3G doesn't sync up with MobileMe.
After some trouble in the beginning MM works fine now between my Powerbook and my iMac but although my MM-settings on the iPhone are correct and set to sync calendars and contacts, it simply doesn't.
I have tried everything on the iPhone:
Push (nothing happens).
Disconnecting push, using manual or automatic (15 min, 30 min, 1 hour).
Deleting my MobileMe account on the phone, thus erasing all contacts and calendars, then retyping everything correctly (and getting no message to suggest otherwise).
ITunes too tells me, that calendars and contacts are sync'ed through MM and I can't sync iCal and Contacts using the cable either.
Also, when I open System/MobileMe/Synchronize/Advanced on either of my computers to see the list of devices connected to my MobileMe, it only shows my computers on that list - not the iPhone!
Can anyone help me with this or do I just have to wait for Apple to realize that MM doesn't work on iPhone 3 (2.2) - which kind of defeats the whole purpose of getting it in the first place?
Thanks,

This is a list of registered computers with your MM account, not a list of registered devices. Your iPhone will not be shown in the list of registered computers, because it isn't a computer.
I thought so, but wanted to mention it in case I was wrong.
Have you tried turning Contacts and Calendars off for over the air syncing with your MM account preferences on your iPhone followed by turning both back on?
I have tried everything I can think of, and that includes the above.
When doing this, however, the phone prompts me to accept that all calendar events and contacts on the phone are erased in order to sync new information from MobileMe.
I accept, but trouble is that no new info comes the other way, although the "spinning wheel" is running for ages.
I can again say, that the iPhone has been set up to MobileMe using the correct password and addres.
Neither Push, nor set intervals or manual sync have worked at any time.
The only way, I can put my calendar and contacts onto it is by deleting the MobileMe account on the phone and syncing via USB

Can someone please help. I noticed that all my calendar events have completely disappeared :( I made sure that under settings "mail/contacts/calendars", that under sync it is "all events". Not working.

Can someone please help. All calendar events have completely disappeared from my iphone. I tried troubleshooting. Made sure that in settings, the "mail/contacts/calendars", that under "sync" it was checked off "all events". But it was like that already. Nothing seems to be working. Are my events lost now? I'm stressing. Lol. Thank you.

Check settings > iCloud > calendars. Is it on or off?

Icloud doesn't sync calendars between devices

We have a number of Macs and idevices sharing the same Apple ID. Recently we noticed that when we create a calendar entry on one of the devices, it doesn't propagate to the others (including the computers) until it's physically synced to the Mac. Is this expected behavior? All computers/devices are running the latest software (10.8.2, 6.1.2). Thank you!

No, it's not normal. On the device that is not syncing calendars with iCloud check Settings>Mail,Contacts,Calendars>Default Calendar. Here be sure you have selected a calendar listed under you iCloud account as your default. If you haven't, make this change, then enter a new event on the device and see if it syncs now.
If your settigs are correct and it still isn't syncing, make sure any events on the device that are not in iCloud are added to your iCloud calendar. Then go to Settings>iCloud, turn Calendars to Off, when prompted choose Delete from My iPhone. Then after a minute or so, turn Calendars back to On to sync your iCloud calendars back to the device. Now enter a new event on the device and see if it syncs properly.

Calendar doesn't sync with exchange 2010

Calendar sync with exchange 2003 but after upgrade to exchange 2010 my Calendar doesn't sync anymore.

Hi and Welcome to the Community!
Can you expand on that please? As in, what exactly, tells you it doesn't sync anymore? Did you re-configure the Desktop Software? If so, what did that present? If not, well, you need to since you've changed your Desktop Organizer app...

I tried to sync my phone and received this message: "iTunes was unable to load data class info from sync services. Reconnect or try again later." Now it doesn't sync calendars because it says I need to download Outlook, which I already have

I have synced my phone to my computer several times. This time i received this message: "iTunes was unable to load data class infor from sync services. Reconnect or try again later." It says if I want to sync calendar I must install Outlook to my computer?? Why does iTunes not recongnize that I already have Outlook installed on my computer?

This worked for me...i did a restore on my computer to take it to a date prior to the last update i did on itunes and now it works just fine. Everytime i do a backup it syncs my Outlook! When a request comes up saying there's a new version of itunes click here to download the latest one DON'T do it.
Here's how to do a restore on your computer:
Create a restore point
A restore point is a representation of a stored state of your computer's system files. You can use a restore point to restore your computer's system files to an earlier point in time. Restore points are automatically created by System Restore weekly and when System Restore detects the beginning of a change to your computer, such as when you install a program or a driver.
System image backups stored on hard disks can also be used for System Restore, just like the restore points created by system protection. Even though system image backups contain both your system files and personal data, your data files won't be affected by System Restore. For more information about system images, see What is a system image? You can create a restore point manually at any time by following the steps below.
Go to the Windows website to watch the video. (1:08)
Click to open System.
In the left pane, click System protection. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Click the System Protection tab, and then click Create.
In the System Protection dialog box, type a description, and then click Create.
For more information about System Restore, see What is System Restore?
I HOPE THIS WORKS!

I have DELETED calendars showing in my iTunes Sync Calendars list!?

iMac late 2009
OSx 10.10.2
iPhone 6 Plus
iOS 8.1.3
Completely Up to Date!
no clouds involved, no calendar subscriptions.
I have had a major problem with my Calendar's calendars, which I have completely repaired using Calendar. During that process, I had to rename a number of calendars in order to keep track of what I was doing - an intermediate diagnostic step. Once I'd gotten everything right, exported all the "good" calendars to .ics files, and deleted ALL CALENDARS - both the good ones and the intermediately named ones - then imported the .ics files back into Calendar... leaving me with ONE FULL SET OF CLEAN CALENDAR data. When I open Calendars on my mac, I see 33 calendars listed on the left side of the window.
My problem now that I'm ready to put my calendars back onto my phone, is that my Calendars Library (library/calendars) still has many of the intermediate calendar files (that have NOT been DELETED) and in iTunes, the list of Calendars includes all these same intermediate calendars, as well as the new calendars that I want to transfer to my phone. I would prefer to "select" "ALL CALENDARS" but I can't do that until I can remove the calendars that were supposed to be deleted/removed in the first place. In other words, I have 33 good, clean Calendars, but there are 71 Calendars in my Calendar Library.
What are the correct steps to remove the Library/Calendars folder so that the iTunes "Sync Calendars" list only shows the 33 good calendars, and not the 38 unwanted (deleted) calendars.
What do I have to do to finish the job?

I have/had the same problem. I tried deleting all the "Library" "Calendar" preference files I could find and like others nothing worked. Like others they would just recreate themselves.
BUT, I did find the solution. Not sure which part worked, but this is what I did.
I quit all the apps, Calendar, and iTunes.
I went into the folder pointed to by job-seeker above:
               <user>
               Library
               Containers
               com.aple.CalendarAgent
               Data
               Library
               Calendars
Manually went through each cached calendar folder and looked in the info.plist for the calendar title listed below "<key>Title</key>" and deleted the parent folders of no longer existent calendars.
Then find an app called "Reminders", open it and you will find all the deleted calendars that you have deleted over the years, they seem to get cached in it, delete them and quit.
Relaunch iTunes and find the deleted calendars in question are gone.
I think you could skip all the above and just try deleting the old calendars from this Reminder app and it may work, but the above is what I did when it worked for me and I do not want to recreate the problem just to verify my theory. ;-)
Hope this helps,
Michael

HT204053 cannot sync calendar on my new ipad mini. my mac and macbook use a .me account for iCloud. How can I change this?

I cannot sync calendar on new ipad mini. My mac desktop and mac book have an old .me icloud account name. Cannot change that so how do I sync?

If you had a passcode set on your iPad your data should be safe. The thief would have to force it into recovery mode and restore it in order to use it, which would completely erase it.
This shouldn't keep your daughter's device from accessing the iCloud account however. If you can no longer sign into the account on iCloud.com from your computer, contact Apple support for assistance.

Mac Book no longer syncs calendar with iPhone or iPad

Since I upgraded to mountain lion my mac book no longer syncs calendars to my iPhone or iPad. I have tried the procedure of deleting the calendar cache in the Library folder to no avail. Any other suggestions?

Sorry, but I don't think I can be of much help on this, as I've switched completely to iCloud for my calendar syncing, and I haven't seen an answer to your problem. Maybe somebody else will come along with an idea.

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:
