Lost all calendar events since 2012 and most before then!

I updated my wife's iPhone to her own iTunes/Apple ID - now any calendar events since 2012 have been deleted and even some of those left i.e. from 2012 and before have been deleted as well.
Whenever I was offered the option to delete/merge/keep items they were kept and not deleted.
I have looked everywhere I can think off, including using iPhone recovery software - and there isn't any sign of deleted calendar events! If they had been deleted as I changed the Apple ID - I would have thought they would all have been deleted! As you can appreciate it, I am now firmly in the dog house! - where have they gone and can I recover them?

Thanks - initially the calendar seemed to be totally empty. I then did as you suggest and discovered the events prior to 2013. It is almost as if there was an incomplete synch and then it synched again and took the incomplete version as the correct version - loosing all 2013 events and some of the events prior to 2013!

I lost all calendar events and contacts during iTunes backup

i lost all calendar events and contacts during iTunes backup
I think my wife had an old apple ID on the phone and never backs up her device. She lost all contacts and calendar events. any help?

It would default to whatever account you have set for default. If you were using Exchange, it would sync to that. However, the settings for syncing are set up in iTunes. You would need to check to see what settings were in iTunes for syncing the information. It could be a supported application on the computer, or a cloud service as I said earlier.
On my personal phone, it will default to my iPhone calendar which I sync with Outlook on my computer. I can select the Exchange account if I want, but my default is what I sync with Outlook.

Just lost all calendar events

Got out of plam Desktop 6.2.2 and then back in, all Calendar items are gone. Contacts are ok. Where is this data stored?
Any sugestions? Thanks, Brad

You can recover the data from your user folder provided you have only sync'ed once with the PC when you discovered the data missing. When you sync to the PC there are files created for each PIM category in your user folder. For Example; datebook.dat or datebook (Depending on the version of Palm Desktop) and datebook.bak. Using 6.2 the file names are .mdb and mdb.bak. For 6.2, the files are located in the username folder in PalmOSdesktop in my documents.
The files for previous versions are named .dat and .bak. When you sync, the current data is stored in .dat. The next time you sync the data in the .dat file is copied to the .bak file. With Palm Desktop closed, you can rename the .dat to .old. then rename the .bak to .dat. If the data in the .bak file is intact, it will now be in palm desktop when you reopen Palm desktop. I have included a link to show you how to find the userfolder on the PC.

Here is another link regarding data loss;

The best way to backup your data is to use the export feature in Palm Desktop. Make a new folder on the PC desktop named Palm Desktop Backup data. Next, select the category you want to export. You will get a window that asks where you want to save the file, save in the folder created on the desktop. There is a button that allows you to select currently selected record or all, select all. If you don't select all, then only the record highlighted is exported. You will then need to name the file for export, I suggest the name of the category, eg: datebook (With current date). Do this for all critical data in each category. With the data exported to the folder on the PC desktop, you can save this data to a flash drive, external hard drive or a CD-RW. With this method you will have your data in a seperate place than Palm desktop and the device. If you "Lose" data again, you can import the data back into palm desktop.
Make sure that when you make changes in palm desktop or the device to export the data to the folder created for the backup.

Lost all Calendar events =(

Hi everybody,
I was adding an event to my Calendar app when it "crashed" and went to my home screen. I opened the app again and all of my events were gone like it was set to factory defaults. I had a ton of stuff in there. My questions are:
1) Do you know why it did this?
2) Is there any way to recover my events?
3) How do I keep it from happening in the future?
My iPhone is version 2.2. I sync it with iTunes, but I don't have it set up to sync with a program like Outlook. I haven't had any other problems with this iPhone except for today. The only thing I did different was charge it using a 3rd party Belkin USB cord last night. Could that have caused it?
Thanks for the help!

one thing that might help.
Try to restore the iphone from back up.

I lost all calendar events with mountain lion -- help!

I upgraded to Mountain Lion, and all looked fine until I opened Calendar -- no events!

Jim,
I presume all of the calendars have a ✓ mark in the appropriate box?
Try removing the com.apple.iCal.plist file from your Macintosh HD/Users/yourusername/Library/Preferences Folder. To find that Library folder, use Finder>Go Menu>Depress the "Option" key>Library. Drag the .plist file to your desktop, and log out/in or restart.
Then go to your Macintosh HD/Users/yourusername/Library/Calendars Folder and remove any files with "Cache" as a part of the file name. Use the same method as listed above to get to the correct Library Folder. Log out/in, or restart and check iCal for functionality.

On the computer go to iTunes>Preferences>Devices and see if a backup is listed. If no backup then unless you backet up to iCloud then, as I said my first reply:
- If you used PhotoStream then try getting them (photos only) from your PhotoStream. See that topic of:

I lost all my events on iphone prior to 2015 and this is not nice as I often need to look back on past dates they are on my Macbook air but how can I get them back to my phone

They're not lost, they simply don't show because you settings ask it not to.
Go to Settings --> Mail, Contacts, Calendar --> Calendar --> Sync --> All events

If the calendar is on iCoud.com, all you would need to do to get it on your phone is go to Settings>iCloud on your phone, sign into your iCoud account and turn Calendars on. The iCloud calendars will then download to your phone.

I have downloaded IOS7 on my iPhone and all calendar events have disappeared. The general functions of the calendar have changed and are definitely not 'user friendly'. How can I retrieve my calendar events. Will Apple improve the calendar function

I have downloaded IOS7 on my iPhone and all calendar events have disappeared. The general functions of the calendar have changed and are definitely not 'user friendly'. How can I retrieve my calendar events. Will Apple improve the calendar function or revert to the previous system. Even the typing function on IOS 7 is faulty - very slow to respond to the keyboard. I no longer enjoy using my iPhone. Can anyone assist. Thank you

Very strange! All of my calendar events have reappeared. This has happened one week after downloading iOS 7
The calendar however, is not easy to use.
The typing function on the phone has become even slower. Have to wait for each letter to show on screen.

Not sure why this happened, but are you syncing calendar events direct with a supported calendar app on your computer?
If not, calendar events are included with your iPhone's backup which is updated by iTunes as the first step during the iTunes sync process. If you haven't synced your iPhone with iTunes since this data went missing, you can try restoring your iPhone with iTunes from your iPhone's backup. Do not sync with iTunes before doing so, and do not update your iPhone's backup before doing so when prompted.

Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. Note that in iTunes 11 an "empty" library may show your past purchases with links to stream or download them.
In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!
Should you be in the unfortunate position where you are no longer able to access your original library, or a backup of it, then see Recover your iTunes library from your iPod or iOS device.
Would you mind telling me which anti-virus package you use? It may be that it is disturbing iTunes when it tries to write out the fresh database, as it does after almost any activity with your library. I'm noticing more of this type of problem than usual and trying to see if there is any pattern. It may help to prevent a repeat of the problem if you look at the advanced options for your AV package and see if you can find a way to exclude the iTunes folder from any real-time scanning process.

Nokia N97 Mini - Calendar events since January 1st...

Hi all!
I´m facing a strange problem my calendar events since January 1st aren´t displayed.
I tried to reset the device (hard reset) but when I recovered the backup I faced the same problem.
Is there anyway to delete just the Calendar data? I am asking it, because I would like to try a full resync (through Mail for Exchange) to try to solve the problem...
1- Anyone faced this problem because of the new year?
2- Anyone knows how to delete just the Calendar data?
I´ll try to backup everything (without calendar), do a new hard reset and then recover the backup without Calendar Items.
I updated all the Firmware available.
Any idea folks?!
Thanks in advance!

Yes, thanks, I tried it too.
The last thing I did: Deleted all the calendar data on device. Sync Google with Outlook (it works) and than sync with the N97 through PC Suite (it works too, but don't solve my problem, because It's bad for me be dependant of Outlook, because I use Multiples PCs and this way, I don't have real time Sync)
I still looking for a better solution.
PS: Before it I tried another software to Sync (in my opinion better than "Mail for Exchange" to Google Calendar: But it does not solve the problem (2010 data).
