Forum Question: iPhone 4 – Outlook “Conflict Resolver” Problem

I have had this “conflict resolver” problem for many months.
When I sync my iPhone 4 (all software current) with iTunes (current version using a PC. Everything works fine except no new contacts or calendar appointments will sync. Using Outlook 2007 SP2 (current as well). This same problem has been going on through a few versions of each of these items.
I have done everything possible including factory default restore for iPhone 4 and deleting and reinstalling iTunes. I am not using mobile me. I have search the online world for solutions as well.
Specifically no new contacts or calendar appointments will sync. Sometimes when I am syncing, I get the “Conflict Resolver” message with 3 contacts to resolve and 38 calendar appointments. It is the same ones everytime. I even get this message after I have wiped clear all the contacts and calendar appointments off my iPhone 4 and after a factory default restore as a new iPhone.
If I try to resolve them by any means including “review later,” the “Conflict Resolver” crashes and I get the following error message box
Cannot Access Conflicts
Unable to retrieve conflict information from the sync server.
Please try again next time the conflict resolver window is presented.
You all are the smartest Apple community on Earth, can you give me some suggestions as what to do? Thank you.

    I’m afraid I can’t offer much help here. I don’t use a PC/Outlook. Is Outlook 2007 the most recent version? Seems like there should be a newer one than 2007.

    The solution is quite simple. Upgrade your iPhone iOS to the latest version, which is version 4.3.3. You can upgrade through your iTunes program. Apple fixed that problem with this latest iOS. That’s what worked for me. Good luck.

    I am now on vers 4.3.5 and the problem persists – Apple, you need to sort this !!

      I’m with Richard, both in version 4.3.5 and opinion that this problem has persisted far too long. Our issue is my wife’s iPhone mated to Outlook on her netbook (Win 7 Starter) iTunes. My same version iPhone is mated to the native apps on my iMac (Lion), which of course behave as expected.

      Given the duration of this issue, it seems this might might be a philosophical disconnect between companies catering to enterprises versus consumers. But increasingly these markets are merging in many respects, particularly with the tools that individuals want at their steady disposal. It would also seem that whichever of Apple or Microsoft resolves this could seize a bit of good press never mind pleasing more than a handful of frustrated users.

    It took me ages to figure this out, but finally I made it through this.
    It turns out it wasn’t an itunes problem (at least in my case).
    Outlook had squirreled away multiple conflicting copies of corrupt appointments in different locations. I had to use windows search (in the start menu) to find all of them and then delete them from the file explorer. Then they showed up in my deleted items folder in Outlook. I deleted them from there and then it was necessary to close outlook and reopen it for them to be completely removed from my system. I noted the calendar appointments I cared about and added them back in after all of that.
    Tedious, but problem solved.

      Hi Michael,
      I’m having the same problem. What search term were you using to find the corrupt Outlook entries? Any help would be appreciated!

      I am still having this issue, what criteria did you use for your search (.cal?)

      5/15/12 @ 5:22 am

      how did you find the corrupted Outlook entries?

    I am having this same problem, but in synching with my iPod Touch. The software is version 4.2.1, and this must be the latest version, since “Check for Update” says I have it. Perhaps Apple is coming out with an update for the Touch that will rectify the problem?

    Now have 17 conflicts and cannot get rid of them. Anyone have an idea?

    To confirm (Iphone4 & Outlook 2007) issue comes from deleted contacts/notes/calendar entries in Outlook.

    Goto Folder View
    Deleted Items
    Delete everything in the folder…or at least the Contacts/Notes/Contacts entries
    Close Outlook

    Tested on two machines with the problem…solved in both cases.

    resolved by conflict for Outlook 2007. I followed the directions, but instead of “disabling” all the stuff that is in there (i’m on an exchange server) I saw that the itunes was on the “disabled” list on the bottom – so I clicked “enable” menu at bottom and seems to have fixed it.

      1/9/12 @ 9:36 am

      Where did you find the “disabled” list and “enable” menu at bottom?

    I have same conflict resolver problem.
    I have tried all above suggestions without success.

    Outlook 2010
    Iphone 4 IOS 5.0.1

    This problem persists with me as well. My iPhone4 is running 5.0.1, the latest (but hopefully not the greatest) software release.

    As I am totally dependent upon Outlook for scheduling, as as Apple seems disinclined to fix this in a timely fashion, I’m now in the process of examining alternatives to the iPhone.

    I had also had this problem for several months with 70 conflicts which would not resolve. Following a tip from this thread, I emptied all my deleted items files in Outlook, not only in my current Outlook files (which I tend to do regularly), but also in my archived files and other folders. If your archived files / folders are not shown in your Outlook today page, you can make them visible by going to File – Data Management, and then adding all your archive files (usually from Users – Your name – Apps Data – Local – Microsoft – Outlook – which is where Microsoft does a good job of trying to hide your Outlook files from you). Once I had emptied all my deleted items files, the problem seemed to go away.

    Thanks Steve Shaw!
    Tried forever and then your hint reminded me that I’d worked on my archived files a few days back and done some cleaning.
    Reloaded the archive pst, emptied deleted items, and Bob’s your uncle!!

    Emptied deleted items
    archive;pst to garbage
    Wonderful It works
    Thanks a lot

    Conflict with calendar, notes and contacts between iTunes and Outlook 2010/Windows 7 persists with IOS 6.1.2 on my iPod Touch 4g and iTunes The suggestions on the list to date have not solved the problem. Today, I uninstalled iTunes, Quicktime, Apple Mobile Driver, Apple App Support, folders “Apple Computer” and “Apple” and all Library.itl files on my computer and re-installed iTunes, but the problem reappears. Any more suggestions?
