Upon Sync of contacts ( Outlook ) with iTunes, I see duplicate contacts being created and it is listed as Share contact. I see multiple contacts like this in my "From My PC" and "iCloud". Please help resolve this problem and how to avoid these duplicate contacts?



iPhone 4S, iOS 5.1.1

    Don't try to sync your contacts using both iCloud and iTunes or you will get duplicates.  Choose one and disable the other.  See

    I Hear you! Thanks. I have deleted duplicate contact in iCloud. Now when I do my next sync in iTunes I should not check mark on back up iCloud?


    I appreciate if you can advise how to disable iCloud since I keep on adding new contacts in outlook and would like to sync to my iPhone.


    Another question, how iCloud will be updated with new contact additions if we disable this?


    Thanks !

    Before I answer, are you syncing your computer with iCloud too, and do you have Outlook 2007 or 2010?

  • factorystation Level 1 (0 points)

    No, I am not syncing my PC with iCloud. I'm using Outlook 2010.

    If you are running Windows Vista with Service Pack 2 or Windows 7 you may want to consider syncing your computer with iCloud, which will enable you to continue to sync your contacts on your phone with iCloud as well as Outlook.  Otherwise you would need to disable syncing contacts on your phone with iCloud and changes to contacts on your phone would only be reflected in Outlook when you sync with iTunes.  (With iCloud changes are pushed to Outlook whenever it is online.)  Let me know if you would prefer to sync this way with iCloud or stay with iTunes and I'll give you the appropriate steps.

    I would rather get your professional advice since I need to sync almost every other day to keep my devices updated. I'm using Window 7 though! How about iTunes Music sync?


    I prefer user friendly proceedure with no mix ups going forward. Please advice your disposition alongside both the proceedures. Thank You so very much.

    I prefer iCloud syncing since it pushes changes between connected devices in real time.  However iCloud does not sync Music, apps, videos or other iTunes media so you would still need to continue syncing with iTunes for those.  If you're okay with this, to make the change you would do the following:

    1. Download and install the iCloud control panel for windows and configure it with your iCloud account as described here:  You will notice that, in addition to contacts, you have the option to also sync your iCloud calendar with Outlook, as well as your iCloud mail, your internet bookmarks, and to enable Photo Stream uploads and downloads if you so choose.  At a minimum, enable contact syncing with Outlook.
    2. Next, prior to connecting your phone, open iTunes and go to Preferences, on the Devices tab check "Prevent...from syncing automatically".  (This prevents and automatic sync when you connect your phone, avoiding the creation of duplicate contacts again.)
    3. Now connect your phone to your computer and click on the name of your phone when it appears in iTunes on the left sidebar.
    4. Go to the Info tab to the right and uncheck Sync Contacts.  If you also selected to sync Calendars, Mail and/or Bookmarks with iCloud you must also uncheck these on the Info tab as well.  (I sync all these using iCloud and have nothing checked on the Info tab)
    5. Click Apply at the bottom to sync your phone.
    6. Go back to iTunes Preferences and re-enable automatic syncing with iTunes if you prefer this.

    Your phone is now set up to sync with iCloud rather than iTunes for whatever services you selected, and you should not longer get duplicates.  Finally, if you are backing up your phone to iCloud (Settings>iCloud>Storage & Backup>iCloud Backup set to On), there is no need to change this.  Your phone will continue to backup to iCloud daily when connected to your charger and wifi is available.


    Let me know if you have any questions about any of this.

    Thank You so very much for the detailed step by step instructions.


    How about if I chose to do sync with iTunes only. As I learned, I can do sync with iCloud on my contacts and still need to do others with iTunes. I may rule out iCloud sync and stick with iTunes only. Therefore, please send me instructions on how to with iTunes only disabling iCloud.


    Thank You!

    You're welcome.  You can only sync contacts with iTunes if you have a supported program on your computer, which for Windows computers includes:

    • Microsoft Outlook 2003, Microsoft Outlook 2007, Microsoft Outlook 2010 (Windows XP, Windows Vista, or Windows 7)
    • Windows Address Book (Windows XP)
    • Windows Contacts (Windows Vista / Windows 7)


    Do you have one of these?

  • randers4 Level 9 (62,715 points)

    Sorry, ignore that.  I had forgotten that you have Outlook.  To sync contacts with Outlook using iTunes:

    1. On your phone, disable contact syncing with iCloud by going to Settings>iCloud and turn Contacts to Off.  You will get a prompt about whether to keep the contacts on your phone or delete them.   To be save, choose to keep them.
    2. Next, prior to connecting your phone, open iTunes and go to Preferences, on the Devices tab check "Prevent...from syncing automatically".  (This prevents and automatic sync when you connect your phone before we check your sync settings.)
    3. Now connect your phone to your computer and click on the name of your phone when it appears in iTunes on the left sidebar.
    4. Go to the Info tab to the right and confirm that you have checked to Sync Contacts with Outlook.  If not, select this.
    5. Now click Apply or Sync, which ever appears at the bottom right of iTunes to sync your phone.

    You may notice that you still have duplicates on your phone now because the duplicates you removed were in iCloud, not Outlook.  If so, you will have to remove the duplicates from Outlook and sync again to finally be rid of them for good.  Also, on your phone open your Contacts and tap Groups on the upper left.  Confirm that if you still have an iCloud group listed that you select the Outlook group instead (may be listed as From my Computer or similar).  Then you should be good to go.

    I did step by step as per your instructions above and sync the iPhone with Outlook contacts. Not only I see the duplicate contacts in my phone but also in Outlook after my this sync.

    You should have chosen to delete the contacts from your iphone and then sync with computer, thereby putting one single contact list on iphone. instead of merging  copy of contacts from iphone  with Outlook creating duplicates


    Clean up dupes on  your computer and start over.

  • randers4 Level 9 (62,715 points)

    To fix this:

    1. Delete the duplicates from Outlook
    2. Prior to connecting your phone disable automatic syncing in iTunes (iTunes>Preferences>Devices> check "Prevent...from syncing automatically")
    3. Connect your phone, click on the name of your phone on the left sidebar of iTunes
    4. On the Info tab and under Advanced: Replace information on this iPhone check Contacts
    5. Click Apply to sync your phone. This will replace the contacts on your phone with the unduplicated contact list from Outlook.
    6. Go back to iTunes preferences and re-enable automatic syncing if you prefer this.
