Itunes could not sync information to the iphone because a sync session could not be started

How to fix this sync problem ?

[Reposting from another, similar thread which I started]
Hey. I "fixed" the issue for myself, although this fix might not be available to you. I have a home laptop and a work desktop both running W7. I was syncing contacts with my work computer because that's where most of my contacts originate, but it isn't essential that I do so. I exported my contact database from my work Outlook to a .pst file, dropped it in Dropbox, came home and loaded the updated contacts, and then synced the phone. It worked fine and I suppose that's how I'll have to do it from now on.
I've had random problems since our company "upgraded" to a Windows Exchange server with user data getting corrupted. After the server pushes updates to our desktops, I've had things like Firefox settings disappearing and such. I assume this was similar and iTunes couldn't find my contact database, or it was corrupted in such a way that it still works fine in Outlook but can't sync. Anyway, I don't have the time or patience to solve this on the work box and I don't know if I ever could. My eventual fix (probably coming soon) will be to buy a 4S
Good luck with your phone. Have you tried a restore?

ITunes cannot sync photos to the iPhone because your iPhoto Library is not yet available.

I've turned my iPhone 4 into a iPod, meaning I only use it to hold music for my workouts. Ever since I've upgraded to Yosmite I can't sync my iPhone 4 to iTunes anymore. I can back it up, but I can't sync. Each time it tells me "iTunes cannot sync photos to the iPhone because your iPhoto Library is not yet available" I don't want to sync any photos, just music.
I've tried to repair my iPhoto Library, restarted my Mac, restarted my iPhone 4 but I still get his error message.
In iTunes when I select my iPhone 4 > Photos, I just get a spinning wheel.
Any thoughts??

I can't follow the first link since I just get a spinning wheel for photos.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
Click the Clear Display icon in the toolbar. Then take an action that isn't working the way you expect. Select any lines that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

My iphone calendar has all and the most updated information. Outlook calendar only shows my recurring events.

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..

The software on iphone has expired + Itunes cannot sync apps to the iphone because the apps installed on the iphone could not be determined + Can't restore = Help!

Hello guys, I'm begging for your help, I've read so many threads, nothing works for me. I hope you will try to help me
First message I get when I connect the iphone is
"The software on iphone has expired and must be updated to a newer version"
Then it tries to backup but I get
"Itunes cannot sync apps to the iphone because the apps installed on the iphone could not be determined"
When I click check for updates it says I have the latest version (5.0)
When I try to restore I always get "iTunes could not backup the iphone because a session could not be started with the iphone. Please disconnect and reconnect the iphone, then try again"
Tried that MANY times but no luck.
This iphone was on a developper account but it is not anymore (removed from developper account).
I'm the administrator on my PC. When I'm on the summary of my iphone it shows N/A as my phone number.
Back up to icloud doesn't work because I didn't set it up before it stopped working
When I try to activate it directly from the iphone I always get "Could not activate iphone. Your iphone could not be activated because the activation server is temporarely unavailable..." (for the past 3 weeks :s)
I can access my music and everything from itunes.
I even tried to restore it from the ispw file (using shift + restore) but I got an error message (sorry I don't remember which one) but it didn't work.
I also tried device manager, select PC, scan hardware for changes (read it worked for some) but not for me after that I don't get the
"The software on iphone has expired and must be updated to a newer version" and "Itunes cannot sync apps to the iphone because the apps installed on the iphone could not be determined" ...I just get "Itunes could not back up iphone because a session could not be started with the iphone" + "itunes could not sync because a connection could not be established with the iphone"
Please help me make it work again! I'd go to an apple store but I'm in south-east asia at the moment and there is nothing like it in 700km +
This little machine would be perfect to travel with, it's a shame it just stopped working like 3 weeks ago, just said I needed to activate it again ...
Thanks a million times!

I can't access it on the iphone as I said
On itunes in summary I have "Software version: 5.0"
Yes I tried to restore it
"When I try to restore I always get "iTunes could not backup the iphone because a session could not be started with the iphone. Please disconnect and reconnect the iphone, then try again" ...did that many times but always the same error message
"I even tried to restore it from the ispw file (using shift + restore) but I got an error message (sorry I don't remember which one) but it didn't work."

My problem - when syncing and error messages comes up: iTunes could not sync calendars to the iPhone because an error occurred while margin data." I've tried turning the phone off and back on, & tried both USB ports but get the same thing. What can I do next since it doesn't give me even one clue as to what the error would be?

Before I started to resync calendars one by one as suggested in the troubleshooting article, I remembered something that came up in a sync when I first attempted : a 'which one do you want to keep' message about a repeating calendar event, which came up with three options, one from Calendar, and two from iCal on the phone. I deleted that event, then went through the calendar resync one by one, and all seems OK now.
In Music there is a way to find 'ghost' items that show up as grayed-out on the menus, so that you can try to reassociate or delete them. It would be nice to have a similar way to work with Calendar!
Thanks for pointing me to the right article.

Itunes could not sync calendars to the iPhone because the iPhone disconnected

Just went to sync my iphone today and got this message:
iTunes could not sync calendars to the iphone because the iphone disconnected.
Any ideas what the problem might be. Had not had this happen to me before.
Can't be iCloud because the only thing I use that for is Find My Mac.
Restarted iTunes as well - still get the warning notice.
Any ideas?

I have the same issue - it just started happening. Any suggestions out there??

When I sync my iPhone5 with my Macbook Pro I get the following message "iTunes could not sync calendars to the iPhone because the iPhone disconnected". The strange this is that the phone did not disconnect because it sync my contacts and is charging.
Why does this happen? I have tried several cables and it does the same thing.

ITunes could not sync contacts to the iPhone because an error occurred

When I connect my iPhone to my iMac (OSX version 10.6.6), and open iTunes and select "sync" - everything syncs (my Apps, Music, Movies, TV Shows, Podcasts, books, Photos and Calendars). However, I get an error message popping up saying: "iTunes could not sync contacts to the iPhone because an error occurred while merging data".
I have unchecked the contacts button in iTunes and then sync works fine.
I have deleted all my contact in my Address Book on my iMac and tried to sync. Again, same error message as above.
I have not tried to restore the iPhone as I am worried to loose my contacts saved on my iPhone.
Who know how to solve this problem? Thanks

Hi Charlotte
I had the same problem for one year now and it affected my contacts, then later my calendar.
I followed the Apple troubleshooting guides and finally managed to make it work again.
First try the following guide:
iPhone, iPad, iPod touch: Troubleshooting contact and calendar syncing via USB on Window
http://support.apple.com/kb/HT1692
For me I noticed that after I updated ITunes to latest version (using the full uninstall from the last point of the guide above, section "Reinstall Apple Mobile Device Support and iTunes"), I could sync with another Windows user account (on another computer actually)
Since I wanted my own account to sync again, I then used the advanced troubleshooting guide:
Advanced troubleshooting for Sync Services on Windows with Microsoft Outlook 2003, Outlook 2007, or Outlook 2010
http://support.apple.com/kb/TS2776
In my case the point 4 in this guide helped, but since I had no MobileMe, I just killed the OS process SyncServer.exe, then renamed the SyncServices folder to SyncServices.old and restarted the PC.
You should try all the steps in both guides in the order mentioned, to see which one can help, I don't advise you to start directly with a step in a guide
Good luck

Same issue. Is this a new bug with iTunes 10.5.1??
Anyone know of a solution?
I reported it to Apple on the feedback page, but, I'm pretty convinced that Apple doesn't listen to or read their feedback. http://www.apple.com/feedback/itunesapp.html
