Syncing calendars to iphone

Recently my calendar will not sync to my iphone. I put it in the dock and then I get the message in itunes saying " syncing calendars with iphone" but the process never gets completed. It stays like this for hours. I have even left it overnight and it still was syncing in the morning. I don't have a large amount of calendar entries either. I tried restoring my iphone and that did not work either.
Any suggestions??

I had a similar problem a while back and someone here helped me through it. That's the good news. The bad news is I don't know who and I don't remember what they said exactly. It was something to the effect of going into iTunes and checking a box to synch calendars. This basically purged my events in the phone and forced a synch of my PC events to the phone. It worked. I believe it was under, as in scroll down, mail items. Play around with that and hopefully the person who helped me will show up again. Good Luck. I know how frustrating this can be.

  • 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.

  • 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.

  • Error while merging data problem while syncing calendars to iPhone

    My iTunes just recently updated itself to iTunes 12, I'm using OS X Mavericks on a Macbook Pro, and have an iPhone 5S with iOS 8.1.1.
    Whenever I try to sync my calendars from my laptop onto my phone, I get a message saying "iTunes cannot sync calendars to iPhone because an error occurred while merging data".  I'm not sure if it's an issue with iTunes or my phone...but everything else syncs normally.
    If anyone could help it would be greatly appreciated!!

    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..

  • Since I down loaded Mavericks I can't sync calendars with iPhone. How can I sync iPhone calendar and Mac calendar

    Since I downloaded Mavericks on my Mac I can't sync calendars with iphone. How can I sync iphone calendars with Mac calendar?

    Mavericks syncs Calendar via iCloud.
    Make sure you have the same iCloud account set up on your mac and your iPhone.
    In System Preferences > iCloud, make sure the Calendars checkbox is checked.
    In System Preferences > Internet Accounts, iCloud should be an account in the box on the left, and Calendars should be checked in the box on the right. If you have other calendars, for example, from work, make sure those are enabled too.
    Check the same settings on your iPhone: in Settings > iCloud, make sure the same iCloud account info is present and that the Calendars slider is on. in Settings > Mail, Contacts, Calendars, make sure the iCloud account is present, and that the Calendars slider is on.

  • Unable to sync calendar from iphone to itunes etc- message coming up

    Hi,
    Since I did an upgrade of itunes on my phone I keep getting this error when trying to sync with my phone and itunes
    "iTunes could not sync calendars to the iphone "iphone" because the sync server failed to sync the iPhone."
    Any advice on how I can sync would be helpful as it is difficult when things arent updated.
    Thanks

    I have the same problem.
    After upgrading to latest iTunes I got an error saying "Itunes cannot run because some of it's required files are missing. Please reinstall iTunes". I fixed this by going into programs, found iTunes, right click and click repair (as detailed here: http://discussions.apple.com/thread.jspa?threadID=2775935&tstart=0 )
    So now I have same problem, iTunes can not sync calendars to the iphone.
    I only ever have problems like this after an upgrade. Very frustrating and time-wasting Apple!

  • 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.

  • Ipad no longer syncs calendar with iphone 6

    My iPad was working fine a few days  ago in syncing calendars with my new iPhone 6; however, I just noticed that when I receive invites [ics] they appear on my iPhone but do not go into the cloud to appear on the iPad.  I tested putting something on my calendar and that appeared on both devices; however, getting a test email from another person, it didn't show.  I signed out/in back into icloud on the iPad and still not syncing.  I feel the sync is broken and I don't know how to get it back. Can someone give me guidance on what to do?  I sync wirelessly on both devices and have also synced the with the cable.  NOTHING.  I use a PC.

  • ITunes wont sync Calendar to iPhone

    Says "iTunes could not sync calendars to the iPhone"XXX iPhone" because an error occurred while sending data from the iPhone."
    I just got the phone about a month ago, when I converted everything from my 2G to 3G the phone seemed a little sluggish, now started doing this, I did a restore and still the same thing.
    Just wondering if anyone knew what I could do to possibly fix this?
    Thanks

    Update your iPhone to 4.2
    In itunes, once your phone is connected, check mark the opinion you want to sync and try it again.

  • "...could not sync calendars because iPhone disconnected."

    Anyone gotten this message? I plug in my iPhone and it shows up in iTunes. I click sync and it starts, but then I get the message that it couldn't sync because the "iPhone disconnected." But it didn't!! I've tried restarting the computer, and even did a restore on the iPhone (grumble, grumble!) but no dice.
    Can't find this in support topics, either. Any suggestions? MUCH appreciated.
    I'm on an iMac with OS 10.4.10, and I have run software update. Also made sure the iPhone was up to date.

    If your iphone will not sync ical and throws an error saying the iphone has disconnected, there are a few steps to follow to see what in ical is kicking out the iphone. There is something ( an event, alert ...) that has become corrupted and itunes does not like it, so it disconnects the iphone.
    Try these steps to narrow down the offending calendar and/or event.
    1. create a new calendar in ical. Name it test, iphone or something.
    2. uncheck all your calendars in ical, so you can only view the events in the new calendar
    3. put a test event in the new calendar ( in the future). Call it Test 1.
    4. connect up your iphone and set the iphone to sync only to that new calendar.
    5. In the info tab that shows up when the iphone is connected, make sure to sync ical calendars is checked
    6. Set it to sync only selected calendars.
    7. in the window that shows all the calendars, only have the new calendar checked.
    8. put a check mark in the box not to sync items older than... Set it to 1 day.
    9. Now click apply in the bottom right side of itunes. (this will see if the iphone can sync to ical)
    10. Once you have established that the iphone can sync, go back into the info tab and uncheck the new calendar created and check only one of your old calendars.
    11. Click apply and try to sync the iphone to that particular calendar.
    12. Keep unchecking a calendar that syncs and check a different calendar until you run across a calendar that does not sync. The one that gives you a disconnect error.
    13. Now that you've narrowed it down to the offending calendar, you know that it has to do with an event from yesterday and forward.
    14. Go back to ical and put a check mark in the calendar that is giving the issue. So now you see the new calendar created and the offending calendar.
    15. Now you need to figure out which event/events that are causing the problem.
    16. Start moving events over a few at a time to the newly created calendar and sync the iphone only to the new calendar. You can move events 2 ways.
    16A. if you have the tray to the side expanded so you can view the details of the event, you can change what calendar it is in.
    16B. At the bottom of ical there is a button to the right that allows you to view all evens in a list view. You can right-click or control-click on the event and move to a different calendar.
    17. Keep following step 16 until you receive the the disconnect error.
    18. When you get the disconnect error again, you know that the last batch of events has the offending, or one of the offending, event/events.
    If you run through all of your calendars and do not receive the disconnected error, then the data that was disconnecting the iphone was older data.
    Also, if the iphone will not sync to the new calendar, you might want to reset your sync history in the isync preferences.
    I hope this helps out a bit.

  • 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. 

  • Syncing Calendars with iPhone via iTunes

    On my iPhone I have calendars from my MobileMe Account and calendars from the sync function in iTunes. This has given my duplicates in many instances. So now I've gone into iTunes to check my settings and see that iCal calendars are only to be synced using MobileMe. Thinking a iTunes sync with no calendars selected would fix this problem, I refigured those settings with only one calendar selected. However, it is taking forever for Calendars to sync with my iPhone.
    What is going on here?

    Turned Calendar Syncing on my iPhone off then back on again. When the iPhone asked to merge calendars I said yes. Fixed the problem.
