Leopard, iPhone, calendars not syncing

I get this error message on both my desktop and my laptop:
"iTunes could not sync calendars to the iPhone "iPhone" because an error occurred while merging data."
As of right now only my iPhone has my current calendars, so I can't overwrite the iPhone calendar. If anything I need to overwrite the Mac's calendar.

I have been having some weird things happening with iSync since upgrading to Leopard on a couple of my Macs. First of all when I try to sync the iPhone now I get a message saying that " iTunes could not sync mail accounts to the iPhone because an error occurred remapping record identifiers" A long call to iPhone support left them baffled too and the problem unresolved. This never happened in Tiger since getting the iPhone back in July, all syncs went just fine. Apple's "solution" right now is to have me turn off syncing the Mail accounts to the iPhone. That doesn't seem right because any account changes now have to be put into the Mac/s and iPhone manually and separately. Needs a fix.
Then trying to add a G5 running Tiger into the list of computers on the iSync chain, ( the other three Macs now running in Leopard ), bought in another raft of problems mainly all machines continuously asking for permission to sync each application/info' file all the time until I stopped the syncing by turning iSync off. Leopard doesn't seem to like Tigers around, I had to take the G5/Tiger OS machine out of the loop.
So hopefully we'll get fixes for these problems unless it's something I am doing wrong now under Leopard........
Any ideas?

IPhone Calendar not syncing correctly with iCal since Lion-install

Since installing Lion, the calendar on my iPhone is not syncing correctly:
Events created on my iPhone don't show on my Mac
Events edited on my iPhone don't change on my Mac
Events that I created in iCal on my Mac, for test-purposes, and then deleted immediately, show up on the iPhone when syncing.
Syncing through iTunes (not MobileMe).
Using WeekCal on my iPone, but it seems that the same is the case with the "original" calendar-app.
No similar experience prior to Lion-install.
iPhone is iOS 4.3.4 -up to date
Any ideas? Does anybody know how to reset the sync, for instance?

Hi, my name is Lucas, i'm an Apple Certified Technitian.
Last couple of weeks i've installed OSX Lion in a few Macs.
But one of them drove me crazy!
I have a Late 2007 White Macbook and i installed OSX Lion last week. I also have an iPhone 4 (Factory Unlocked) that i also updated to IOS 4.3.5 ... no problems syncing between them
Then i did the same with a 13'' Unibody MacBook Pro and an iPhone 4 (not unlocked)... no problems neither
Yesterday i installed Lion on a Mid2010 15" MacBook Pro and updated another iPhone 4 (Factory Unlocked) to IOS 4.3.5 and when i tried to sync the iphone with iTunes 10.4 nothing happened.
I mean, nothing.. the iTunes started syncing and when it gets to sync the calendars it stayied there forever.
I left it for hours and nothing.
As i said i'm an ACT so i tried everything.
1- Remove Calendars from iPhone and syncing again
1- Repair Permittions
2- Reinstall iTunes
3- Reset iTunes and iCal Preferences and Caches
4- Backup iCal - erase ical content and generate a new iCal database
5- Reset Syncing Prefs and logs
6- Use DiskWarrior from an external OSX
7- Reset PRAM
Nothing worked.
I thought it could be some conflict with Microsoft Outlook and/or Exchange server since this Mac is the only one of the three macs i installed that uses Outlook Sync and Exchange server and it's the only one that gave me trouble.
But disableing it didn't worked neither.
THE SOLUTION
I Already solved this thing out. But i still don't understand the logic of all this... anyway, what y did is this:
1- turn off microsoft outlook sync with iCal (from outlook preferences)
2- Backed up iCals (Just in case)
3- Create a new Calendar Category (by default you have Work and Home... i created one called Test)
4- i Created a new task at that calendar
5- In iTunes uncheck the "Sync iCal" box and sync the iPhone
6- Check th "Sync iCal" box, then check the "sync the selected calendars" box
7- Check the "Test" calendar and sync the iPhone.
This worked so i started creating task in this Test Calendar both in iphone and mac, just to test it, Worked fine.
Then i selected all the other calendars (Home - Work - etc) and i turned on the outlook sync
Then i synced the iPhone and Voilà everything is working again.
Now i can create task in outlook calendar and when y sync the iphone it appears on it.
I don't know what the problem is... but this looks like the solution
HOpe it works for you!

IPhone calendar not syncing

Please help. I am at my wit's end. I cannot get my iPhone calendar to sync to icloud nor to my Mac. Sometimes some events from my phone sync, sometimes not. I cannot figure out how to get everything to go where it should. iCloud and iCal seem to be in sync. New events from my phone do not sync. I have searched every thread I can find on the subject, no help for me. I do not use Outlook nor google calendars. Just iPhone, iCal, and iCloud. I only started using iCloud because it seemed to be the answer to this problem when my phone stopped syncing to iCal. It still doesn't work. I have tried turning off all my calendars, signing out of iCloud in my Mac's System Preferences, changing how far back events on my phone will sync, all to no avail.

I had the same problem too with certain calendars not syncing. I deleted my MobileMe account from my iPhone and then added it back again. All my data including the calendars that were not syncing repopulated my iPhone in just a few minutes. Everything seems to be working fine now.

IPhone calendar not syncing to iCal or MobileMe

Using Lion and the latest software version on my iPhone: syncing iCal to MobileMe works in either direction. However, when a calendar event is typed on my iPhone it does not sync to anything on my iMac. Does anyone know of a solution?

FOUND THE ISSUE.
Check to see if your Gmail (or mail) is connected to your calendar. If it is, turn it off.
When using Siri, she was scheduling to my Gmail Calendar (which is also where the rest of my meetings were scheduled) That calendar would not sync with iCal on my computer.
So, on your iphone go to Settings>Mail, Contact, Calendars
Look under ACCOUNTS. There should be an iCloud account and your Mail account (Gmail, Yahoo etc)
Click on the mail account and look at the calendars. If they are ON, click them OFF.
Now if you go back to iCal on your phone, you will only see iCloud calendars listed under Calendars. So from now on, when you make a meeting with Siri, she will schedule it and it will appear moments later in iCal on your Computer.
FINALLY!

IPhone Calendar not syncing to iCloud

I am running 8.0.2 on my iPhone 5c and when I add an event or appointment on my calendar, it does not sync with iCloud. When I add an appointment from icloud.com or from Outlook on my computer, it works and will sync to my phone. Just not when I add an appointment from iPhone.
Help please?
Thanks.

Howdy jandally,
It sounds like you are adding events to your iPhone 5c calendar, but they do not sync up to iCloud, but adding them to iCloud.com does sync to the phone. I would use the iOS troubleshooting section of the following article to help you get that going again, named:
iCloud: Troubleshooting iCloud Calendar
Thank you for using Apple Support Communities.
Take care,
Sterling

IPhone Calendar not syncing over the air

My iCal calendars won't sync with my iPhone as of a few days ago after I did a reset. I have tried the following to fix it:
1. Deregistering the computer from Mobile me
2. Resetting sync history in Mobile Me
3. Resetting sync history in iSync
4. Deleting the mobile me account from the iPhone and re-adding it
5. Setting up a test account which was able to sync fine with the iPhone
6. I also tried adding my wife's mobile me account to my iphone and sync'd her calendars and they sync'd fine to my iphone
7. I used her iPhone and added my mobile me account to her iPhone and my calendars sync'd fine to her iPhone
The problem seems to be specific to my mobile me account and my iPhone. Basically the calendars don't sync at all so currently I have nothing but the default calendars on my iPhone. The contacts and bookmarks sync fine.
Any ideas for what I could try to fix?

Hey Lynda Jo,
That is not very productive when the calendars are not syncing. I am not sure what troubleshooting you have done on your end but let’s start with the first article below to get it sorted out. It will have you check the settings even though you have not changed anything, it may be a good idea to double check. If all looks good after that troubleshooting, then the second article will be your follow up to get it working again.

IPhone calendar not syncing to MacBook air

Ever since I upgraded my iPhone to 8.1.3, my calendar entries and deletions are not updating on my MacBook Air with OS Yosemite AND on my iPad (also upgraded to iOS 8.1.3). Nothing has changed in any of my iCloud settings on none of the devices. So obviously the changes that I make with my iPhone are not making it to my MacBook or iPad. HELP!

Iphone calendar not syncing to cloud

My calendar is syncing from ipad to mac to cloud and vice versa. The sync is not working on my iphone 5.

First check that all your settings are correct, that calendar syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the calendars you are using are in your 'iCloud' account and not an 'On My Mac', 'On My Phone' or other non iCloud account (you can do this by clicking/tapping the calendar button in the top left corner of the application ), non iCloud calendars will not sync.
If you are sure that everything is set up correctly and your calendars are in the iCloud account, you might try unchecking calendar syncing in the iCloud settings, restarting your device and then re-enabling calendar syncing settings.

Why isn't my iPhone calendar not syncing with my iPad 2

Issue with Calendar not syncing with iPhone 3g

Issue with Calendar not syncing with iPhone 3g.
Solution
Create backup of your entire mailbox before starting (THIS IS IMPORTANT)
Create offline folder (.pst file) Check windows help on how to do this for your version.
Open folders view on Outlook
Right click on Calendar in tree view and 'copy to' offline .pst folder
Go back to main calendar view and delete all entries in your calendar.
Create simple cal entry and sync test with iphone
If this works then start dragging cal entries back from the offline folder into the main calendar then sync after each step....
I moved events in this order
-Yearly recurrences (ie Birthdays)
- Monthly recurrences
- weekly recurrences
- Daily recurrences
All appointments from the beginning of this year >> to the end of time!
If all these sync then the issue is with an older cal item and you have to decide if you actually need these in you current calendar.
I chose to leave these in the offline cal and if i need access them from there.
If at any point the sync fails then you know you have a corrupt cal entry in the block you just transferred. Move the offending items back into the offline folder and try again in smaller chunks until you identify the offending items and delete them and manually recreate them in your real calendar.
Also smart to run the inbox (.pst /.ost ) repair tools for your OS/Outlook version.
Fixed so far
XP Pro / Outlook 2008
XP Pro /Outlook 2003

I just updated the firmware to iPhone 2.0.1 and the syncing works great both ways.

My 3G unlocked iPhone is not syncing mail or contacts from my mac book pro, using Lion. I am able to get a calendars and music, only. I get the message that I need to reset the password which I have done 3x's on the phone and on the Apple server.

Good to know that, but what can I do to get the mail and contacts downloaded from Icloud onto my Iphone? I am told that the password needs to be reset and I have erased and reset it 3x's already? Should I Restore All Settings or Restore Network Settings or will that result in a situation where I have to have it re-unlocked again? GRACIAS!

IPhone 3G not Syncing with Outlook Calendar 2007

Can anyone help, since updating iTunes to version 8.1.0.52 my iPhone will not sync with Outlook Calendar 2007. I have deleted itunes and re-installed as per Apples instructions and this has no effect. Everything was fine up to the point of updating iTunes. iPhone syncs with everything else just fine.
Regards
Phil

I am having the same problem since last update. I thought it was my wife's sync with a Nokia but after deleting that sync it still is not happening and trying to sync the calendar events for hours. Would love for iTunes to fix the problem.
Does anyone know if you can download an old version of iTunes? Regards Lee

Hi
I have the a similar problem - only I can't actually get the calendar to show up. I've added the account and it's showing Mail and Notes but not Calendar. But I'd like it to show the outlook calendar.
I'm going to
Go to settings > mail contacts calendar
select your account that's affected
But under that account there isn't a calendar showing and I can't see any options to add it?

IPhone does not sync calendar and contact information

iPhone has not synced calendar or contact info entered on the phone with iCal or Address Book. Has shown NO updating in either app since mid-February. Since that time, have updated to iTunes 7.6 and, IIRC, OS X 10.5.2. This is a problem!!
<Edited by Moderator>
Thanks!

Do all Lessons as described by you - dont sync.
Have tested it with several different contact groups or single new contacts. Did it several times (resetting sync history and editing new groups contacts).
Also checked those boxes to overwrite iPhone Entries by the Computer.
Nothing appears on the iPhone.....

My iPad and iPhone do not sync up my appointment calendar

my iPad and iPhone do not sync up my appointment calendar

Go to Settings->Mail,Contacts,Calendars and scroll down to Calendar. For both iPhone and iPad, make sure that the default calendar is NOT "Calendar" but is the same one of those listed under iCloud, preferably "Home". (and of course follow the other advice on functions that are "on".
