Itunes Conflict Resolver sync error: "Unable to retrieve conflict information from the sync server"

Have you any anti-virus software? If so, either give iTunes an exception, or momentarily uninstall the software.

Hi Alex,

I found the fix!!

I was having the same issues for months and was not able to resolve it until last night.

I discovered the solution purely by accident while trying to resolve the issue and it is so simple you will laugh.

CLOSE MS-OUTLOOK

I was looking at all of the recommendaed fix's and I thought to myself, I wonder if the issues is a record lock?

I closed MS-Outlook and ran the Sync again and no conflict sync errors appeared. To test this out again I went to get my iPad and ran a Sync and low and behold no more conflict Sync errors.

Perhaps this solution will work for you also.

All the best!

Dwight

Thanks, DwightM! This has been bugging me for weeks and my own calls to Apple Support were getting me nowhere. I closed Outlook, waited for it to drop out of my system tray, and ran a sync on my iPad 2. It failed! I was disappointed, but for some reason decided to run the sync over again. It worked like a charm. I then hooked up my iPhone 4S, ran sync, and it, too, worked without the error message. I'm not an IT guy at all, so I have no clue why it didn't work the first time, but it's working now. Thanks for sharing the idea! Bill

This didn't work for me.

Though the error did not present itself until I tried it with Outlook open again, the synch failed to update my iphone & Outlook.

The fix above works fine you will need to shut down Outlook and sync twice. The first sync after shutting down Outlook gives the same error message but goes away on the second sync.

I started Outlook again and the problem returns however I did notice that the sync is working regardless of the error. I added and deleted contacts from both my iPhone 5S and Outlook and did the sync with the error message but the contact addition and subtraction still happened.

Sometimes it works, sometimes it doesn't! I keep trying until it does. 😕

I ended up looking at each of my 25 conflicts, removing the conflicting appt from outlook, then choosing the iphone appt as the one to keep (all of the appointments were old, so I really don't need any of them). This appears to have worked; I've re-synced twice, once after restarting my computer. One thing I noticed: in the middle of troubleshooting this, the phone stopped backing up automatically (maybe it wiill only do it once in an hour or something??), so I hit the "backup now". After I resolved the problem on my iphone, I plugged in my iPad (which was having the same problem), and it synced fine, also.

Now if I could figure out how the he** to find my bookmarked discussions, I'd be over my current frustrations! I followed the breadcrumbs I heard about after the recent changes to this site, but my bookmarks page wont come up...

I tried the manual thing but that for me was a waste of time since I got caught in a conflict resolver unable to connect issue all over again

I found something that should help with old calendar conflicts. Connect your IOS device to iTunes and then click on the device in iTunes and choose Info. This will bring up your Mail client (MS Outlook in my case) sync options. Be sure that the check box for 'Do not sync Events older than XX days" is checked and you get to choose how far back you want iTunes to sync with your Mail client Calendar. I set my value to 30, and then applied the change. My next sync did not raise any old calendar conflicts.

Enjoy...

Hi Folks,

The issue seems to be due to a stale control file.

Please check out the post by Gator5000e titled iPhone sync conflict on this same site with the date of Oct 18, 2011 11:17 AM.

That solution seems to work.

God Luck,

Thanks Dwight and WillI'mnot!

After the second try, mine synched without the message popping up. I'm still not sure that it is fixed or that it may have just disabled the conflict resolver.

Time will tell. I'm just pleased to avoid the issue.

Thanks guys.

Worked for me too!
