Suddenly won't sync all Contacts and Calendars

I’ve been syncing my iPhone 2G with Mail, Contacts and Calendar on Outlook 2007 via USB for over a year without any problems. I recently added a Microsoft Exchange email account to Outlook on my PC but I use it only for email. The Exchange email account is NOT set up to sync with my iPhone. The Calendar and Contacts I use are in an Outlook Personal Folder and not the Contacts and Calendar associated with the Exchange account.
Ever since installing the Exchange account, the iPhone does not recognize my original Contacts and Calendar and is not syncing them. Instead it seems to sync the Exchange Contacts and Calendar, which are empty so now my phone has not Contact or Calendar data.
I have tried replacing Contacts and Calendar using the iTunes/Info/Advanced option but that didn’t work.
In iTunes/Info/Contacts and iTunes/Info/Calendars I don’t have an option to select multiple contact lists or calendars to synch.
How can I get it back to syncing the Contacts and Calendar I actually need?
Thanks

I have the exact same problem and it drives me mad - thanks for letting me know if you find a solution. Here is what I will try: export all my contacts from where they are in the pst file in outlook then "try" to reimport them in the ost file (exchange). I noticed indeed that if I create a contact in the ost file, it does get pushed over to itunes.
But there seems to be no way of telling itunes which outlook data file to use in priority, and if you select it as default in outlook you wipe out the content of your mail file on the exchange server. Not great.

ITunes won't sync my contacts and calendars

Hello all,
I'm having some trouble syncing my contacts and calendars to my iPod, because iTunes say's it doesn't have any available, and then it asks me to open that application.
This started after I forcibly shut down my computer.
I've tried replacing the information by deleting all of my contacts and calendars, and restoring using the Backup application, and I still got the same message asking me if I wan't to open iCal/Address Book.
Any solution will be appreciated.

The most likely solution is to launch iSync
application ,and then in the preferences menu, click
on Reset Sync History button. This resets
configurations for the iTunes iPod sync process that
is dependent on the iSync system database system.
Is this the only way to do this? I am sic and tired of reseting my sync data as .Mac seams to have plenty of it's own issues. I use several computers Two for work and an extra at the office and one extra at home that I would have to then on the next sync accept all of the diolog boxes to get the most recent sync data on each computer. What a pain in the ... Not something that I want to do again as I have done it about 4+ times in the last month.

ITunes won't sync my contacts and calendar

When I try to sync my iPad or iPhone, it says "syncing contacts with ipad" or, if I disable that, "syncing calendar with ipad" for 30 minutes to an hour. When it finally stops, I find that it never actually synced anything.
I don't see any other topics on this, but it is seriously frustrating. Can someone PLEASE address this issue???
BTW, it backs up just fine.
Thanks.

You might try using calDAV through google to manage calendar and contacts functionality. When you add the google account to the iPad, be sure to select "other" as the account type rather than yahoo, google, aim, mobileme, etc. so you can instruct it specifically to sync the calendar. A websearch on how to setup the calDAV to sync your google calendar to iCal should return something residing in the google.com realm with setup instructions. Once you get it setup properly - it won't care when you enter/change schedule info, it'll keep them in sync.
Hope this helps,

I caught my phone 4. Had to buy a new one, lost all contacts, and calendar photos. how can I recover them

I caught my phone 4. Had to buy a new one, lost all contacts, and calendar photos. how can I recover them?

What does "I caught my phone 4" mean?
All contacts, calendars, photos etc should be on your computer as the iphone is designed to be synced to your computer.
Just sync them to your new iphone.

ICloud for Windows 8 doesn't sync my contacts and calendar

Hi,
iCloud for Windows 8 doen't want to sync my contacts and calendar with the local Windows 8 programs.
Look at the first line:
What's wrong?
Thanks in advance for your help, and sorry for my bad English!

No, it's "Calendar" from Microsoft Corporation, and "Contacts" from Microsoft Corporation.
They are Windows 8 Modern UI apps, which are installed with Windows 8.1.

TS1347 I had to get a new hard drive on my laptop PC. Now I am unable to sync my contacts and calendar from my iphone to the outlook software on my PC. Although they are backed up on icloud, I really want the information on my computer.

I cannot figure out how to sync my contacts and calendar from my iphone with my windows PC. The message during the itunes sync process is that information is being backed up to both the cloud and my PC. However the Outlook software remains blank. What can I do??

Our exchange server crashed and we lost all contact and calendar data. We found an app to get the contacts off of people's phone to import but can't find the same for calendar. How do I get my calendar info off my phone and in to new exchange server?

You'd have to think through this, but it seems like if you are using Outlook, and the items vanished from the Outlook client as well as the server,that you could re-populate Outlook using iTunes.

Apparently Sync Manager is turned off for syncing my contacts and calendar to using Blackberry Desktop Software - how can I switch it ON?

I upgraded to Mac OS 10.9 a few months ago.
Up till then I was happily able to sync mac Contacts and Calendar to my Blackberry Curve 9320 via Blackberry's Desktop Manager (for Mac).
Since upgrading the software tells me to that Mac Sync Manager is turned off. I know it isn't because everything else is syncing.
When I hunt through your support I find that there are solutions for this problem for other Mac OS versions but not for Maverick, so please tell me how I can once again use my business phone happily as I did before upgrading!
Many thanks
Janet

BlackBerry Desktop Software utilizes Apple's SyncServices technology in order to synchronize Contact, Calendar, Notes, and Tasks information to and from the Mac computer.
BlackBerry Desktop Software synchronizes information with the SyncServices database, which is synchronized with the desktop applications on the Mac computer (for example: Apple Address Book, iCal, Apple Mail, Microsoft Outlook for Mac). BlackBerry Desktop Software does not synchronize directly to or from the desktop applications on the Mac computer.
Mac OS X Mavericks v10.9 and later does not use SyncServices, therefore, it is not possible to synchronize Contact or Calendar information using the BlackBerry Desktop Software on these versions of OS X.
For more information on SyncServices and OS X Mavericks, see the following Apple Support article:
http://support.apple.com/kb/HT5847
Note: BlackBerry Desktop software 2.4 is still supported for use with Mac OS X v10.6, 10.7, and 10.8.

Upgrade to 10.7.5. See:
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor

How can I delete all Contact and Calendar entries on my iPhone so I re-sync from my PC

My Contacts and Calendar are messed-up on my iPhone with literally hundreds of duplicate and erroneous entries. The data is okay on my PC so I wish to clear the IPhone entries completely and then use Sync again to download from my PC. How can I clear the iPhone files?

Looking for reliable sync for contacts and calendar

Does anyone know of a reliable app that will sync contacts and calendars between my droid and my pc? I use outlook (not exchange). I have no problems syncing gmail and webmail. I tried Missing Sync but it won't bring contacts from my phone to my pc and it really doesn't sync. It creates duplicates on my phone while bringing nothing to my pc.
The operative word here is reliable.

Hi. I have my Microsoft Outlook synced to my google calendar which syncs to my iCal on my MacBook which then syncs to my Droid! LOL, a lot of different calendars but I use my PC for some things and my Mac for other things but I want them all to work together and it does with the google calendar. You can go to google, read the calendar section and it's pretty easy to set up. I have bells and whistles going off for birthdays and appointments but I never miss an event.
Good luck!

Anybody knows why my iPod 160 GB suddenly won't sync my Contacts anymore?

It was working alright before I "upgraded" to Snow Leopard and iTunes 9... suddenly I cannot sync my contacts into my iPod (a VERY valuable feature!)... I have been to MacStores and they have no idea... any solutions out there?
Thanks!

Hi
I have a similar problem. Everything went fine, but after installing Snow and Itunes 9.1 My ipod classic 80 GB did not sync Contacts and Calendars anymore. There is also a problem with the battery suddenly.
After having fully charged and I open music after 2 minutes it completely goes blank telling me there is a very low battery status. I do not know if this is by accident or it also hve to do with all the hardware problems people encounter with the iTunes 9.0
Does anybody have the same problem with battery?
thks

All Contacts and Calendars entries have disappreared

All my Contacts and Calendar entries have suddenly disappeared from my iPhone4S, and the phone won't allow me to make any new Calendar entries. I've tried restoring from a back-up on my PC, but I get a messsage on iTunes on the PC saying no back-up is stored there, although I'm looking at the iTunes screen telling me when the last back-up was made.
Any suggestions would be much appreciated.
TIA

How to delete all contacts and calendar events?

I had previously told my iPod Touch to sync my contacts, calendars, and e-mail accounts with my computer (Mac) and sync via MobileMe. Now, I'm giving away my iPod Touch and I don't want to new owners to have access to my calendar, contacts, and mail. I've gotten rid of the mail by deleting all my accounts, and in iTunes I've stopped syncing of calendars, contacts, and mail, but there's still my contacts and calendar on my iPod. Is this because of MobileMe or just because it didn't take them off the iPod? How can I stop MobileMe syncing to my iPod Touch and get rid of my contacts and calendars off my iPod without having to just go one by one and delete them?

Delete an account from iPod touch: Choose “Settings > Mail, Contacts, Calendars,” choose an account, then scroll down and tap Delete Account.
Deleting an account means you can no longer access the account with your iPod touch. All email and the contacts, calendar, and bookmark information synced with the account are removed from iPod touch. However, deleting an account doesn’t remove the account or its associated information from your computer.
