itunes could not sync contacts / calendar to the iphone "---" because the sync server failed to sync the iphone

i have read just about every support entry to this so PLEASE don't respond unless you've read the scenario.

win8.1

itunes 11.4

iphone 4 (last of the os7.1.2) (os8 won't work on the 4)

outlook 2010 (up to date)

so until either thursday or friday, syncing via itunes has been great. then i start getting the error dialogue box. this is what i've done / tried:

changed the USB cable

reset sync history - (done all the various steps of reset / delete / restart / unplug etc.)

deleted backup

repaired all apple related programs in the control panel>programs and features

saved outlook contacts and calendar as a new .pst

created a new user

unchecked advance option in INFO in itunes (that whole scenario did nothing)

signed up with icloud and it worked BUT i LOATHE icloud (and all the hassles it presents) and the bottom line sync with itunes 'should' work.

i have checked all errors within contacts (none i only have 170)

uninstalled / reinstall of itunes

i have NOT done a restore of iphone. (last resort) and hoping that there would be a solution before going there.

so there you have it. any suggestions would be really appreciated.

iPhone 4, Windows 8, outlook 2010

I'm still touching wood, but after hours of wasted time I think this has worked for me too!

Many thanks.

I have the same problem.

Win 7 (64 bit), Itunes 11.4, Iphone 5, IOS 8.

Since I have upgraded my Iphone to IOS 8, while I syncing my device (both on Wifi or cable), I keep getting the following message:

"Itunes could not sync calendars to [my] Iphone because the sync server failed to snc the Iphone".

I don't have any problem with syncing my Ipad 2 ( which was also upgraded to IOS 8), neither had I any problem syncing my Iphone 5 before IOS 8 upgrade.

So it's quite clear that the problem has to do with the IOS 8 upgrade, which somehow broke the connection between the device and the sync server.

Any idea how to fix it?

Thanks.

I didn't have any problem with OS7. Trouble begun only after upgrading my Iphone 5 to OS8 and Itunes to 11.4.

Again - I have no problems with syncing my Ipad 2: calender, bookmarks and notes sync smoothly.

The message appear - and calendar, bookmarks and noted don't sync - only when syncing my Iphone 5.

I hope it's clear now.

not to sound like a twit, but PLEASE do not add links that 'solve' issues without trying them. PLUS i had written that i had iOS7 much less HAD tried this solution already.

it's really important to read posts BEFORE replying to them.

FINALLY - this fixed it.

be sure to restart WITHOUT the iphone attached to be able to rename (which re-creates a new SyncServices folder) the SyncServices folder...

Rename the SyncServices folder.

Disconnect any iPhone, iPad, or iPod touch.
Restart the computer.
To rename the SyncServices folder:
Windows Vista and Windows 7 or Windows 8 : SyncServices is stored in a hidden folder named AppData. The location is \Users\(username)\AppData\Roaming\Apple Computer\

Note: To quickly access the AppData folder, click Start, and then in the search bar type %appdata% and press the Return key.

then connect iphone, open itunes / go to INFO and tick the boxes for contacts and calendars and then in ADVANCE click replace contacts and calendar.

i can sleep now.

Thank you very much.

I have located the folder.

Could you please elaborate on the renaming process of the folder? Which new name should I assign to that folder?

a new folder is automatically created. if this clears your issue after a few days you can delete the old (the one you renamed) folder.

It seems that Itunes 12.0.1 solved the problem.

Wait a minute! iTunes 12.0.1 CAUSED the problem.

here is the sequence: Apple signaled new iTunes available, I agree to download. on the download page I see the size of the download. as I was on a very slow connection, I clicked quit. then **** broke loose.

1) the laptop crashed, then got back

2) then the iPhone refused to sync cause "corrupted backup or incompatible"

3) I presumed that iTunes 12 would solve the problem, downloaded it but still no sync

4) I discovered that the name of my iPhone was changed to simply "iPhone", in iTunes and in the phone !?

5) I discovered that a backup was made just before the crash under the new name

6) I deleted the recent backups to eliminate the corrupted one

7) I ran the iTunes diagnosis on connectivity and sync that mentioned "no problem"

8) I tried in vain to sync 4x

9) I found jdubz post here and it worked

10) I lost 8 hours on this and am pretty p...off

11) I postpone to change to iPhone 6, as for me: "no sync = no use"
