Calendars not syncing on iPhone 4S

A few days ago I realized that events created on my home Mac were no longer syncing through iCloud to my phone. This had been working perfectly through MobileMe since November (when I purchased the phone), and also on iCloud after I made the switch in March. It seems that the problems arrived in mid-May with the release and update to iOS 5.1.1, which seems to have solved my iCloud battery drain issue by making it not sync at all anymore.
I know I'm not the only person experiencing problems with iCloud syncing, but I'm not seeing this problem specifically in the discussions. It has basically rendered my phone's calendar completely useless, as entries are not syncing to or from the phone, and this is a serious problem for usage. I've tried and tested all the standard fixes such as restarting, forcing refreshes, turning off/on iCloud, etc. with no results (or an occasional event syncing, but not the majority).
All syncing is working across my other devices (iMac, MacBook, and iCloud.com).
Is there any fix to this, or do I just have to wait for iOS 6 and pray?

Isn't that always the way things go. So not two minutes after I posted this question I found the culprit that was causing my problem.
My phone was set to sync "Events 2 Weeks Back", which apparently doesn't sync anything past that point (useful, huh?). Switching this setting (Settings>Mail, Contacts, Calendars>Calendars>Sync) to "All Events" immediately caused all of my events to show up, although it seems I may have lost some events created on my phone in the process.
Not a huge deal though, and maybe this will help someone else, as I haven't seen this setting mentioned in the other troubleshooting posts.

Issue with Calendar not syncing with iPhone 3g

Issue with Calendar not syncing with iPhone 3g.
Solution
Create backup of your entire mailbox before starting (THIS IS IMPORTANT)
Create offline folder (.pst file) Check windows help on how to do this for your version.
Open folders view on Outlook
Right click on Calendar in tree view and 'copy to' offline .pst folder
Go back to main calendar view and delete all entries in your calendar.
Create simple cal entry and sync test with iphone
If this works then start dragging cal entries back from the offline folder into the main calendar then sync after each step....
I moved events in this order
-Yearly recurrences (ie Birthdays)
- Monthly recurrences
- weekly recurrences
- Daily recurrences
All appointments from the beginning of this year >> to the end of time!
If all these sync then the issue is with an older cal item and you have to decide if you actually need these in you current calendar.
I chose to leave these in the offline cal and if i need access them from there.
If at any point the sync fails then you know you have a corrupt cal entry in the block you just transferred. Move the offending items back into the offline folder and try again in smaller chunks until you identify the offending items and delete them and manually recreate them in your real calendar.
Also smart to run the inbox (.pst /.ost ) repair tools for your OS/Outlook version.
Fixed so far
XP Pro / Outlook 2008
XP Pro /Outlook 2003

I just updated the firmware to iPhone 2.0.1 and the syncing works great both ways.

Microsolft 2003 calendar not syncing with iphone (using itunes)

Basics: I have Win XP Pro, I use Microsoft 2003, I have an iphone 3G, and I sync my contacts, calendar, and notes using itunes 9.0.3. I don't use Outlook mail and don't sync using MS Exchange -- I just connect my iphone to the computer using a usb and sync with itunes.
Up until a week or two ago, I had no problems syncing. Now, while contacts and notes syncs fine, calendar does not sync at all (in either direction), even though itunes says it's "syncing calendar". I know this is not new (I see many posts about this), and I have scoured the discussion pages for advice already and tried everything I could. I looked at the following apple troubleshooting page and tried everything there: http://support.apple.com/kb/ht1692. Specifically, this is what I have already done and nothing has worked:
* I uninstalled the newest version of itunes (as well as quick time, bonjour, and the other software components that apple recommended I uninstall) and reinstalled 9.0.3
* I uninstalled my Outlook 2003 and reinstalled
* From itunes preferences, under devices, I "reset sync history" (and I have continued to do this before syncing after I try something new)
* From itunes help, I ran "diagnostics" for "iphone sync tests" and no problems were noted. I have done this several times.
* From within Outlook help, I ran "detect and repair" and no problems were noted
* From within Outlook tools and advanced options, I clicked the "COM add-ins" button and removed 3rd party software
HOWEVER...the apple troubleshooting page referenced above suggested syncing content in a new user window, and that DID work! Moreover, when I copied my original Outlook.pst file to the new user account, the trouble starts again and no calendar syncing. And to continue the test, when I remove the original Outlook.pst and put back the new Outlook.pst file in the new user window, it works again. And for the final test, when I copy the new user Outlook.pst file to my main/real user account, the sync works perfectly. All this indicates the original Outlook.pst file is corrupted.
HOWEVER, Apple offers NO advice as to what to do next. The following is quoted from their troubleshooting page:
"Once you are logged into the new user account, create a few test contacts and/or calendar events in your compatible application of choice and attempt to sync that data to your iPhone or iPod touch. Does this newly created data sync properly? If so, you likely have an issue with your content in the original user which you will need to isolate."
Sooooo...what to do now? How do I "isolate" the problem any further?
Any advice would be much appreciated!!!

After fiddling a little more, the following fixed my corrupted outlook.pst file:
1) I made a backup
2) In outlook under file, I exported the calendar to excel
3) In outlook under file, I imported the calendar back to outlook
And voila, it worked.

Google Calendars not syncing to iPhone 6

As of about 3 days ago my google calendars stopped syncing to my iPhone 6 using iOS 8.1.1. I noticed some events were not syncing, going both directions. I removed Calendar Sync from my google gmail account, which deleted all of my google calendars for that account. Then I added calendar sync again. When I did that the calendars do not appear in my iOS calendars app. I've tried to refresh, i've deleted and added several times, but no calendars. I've even posted on the Google support page (https://productforums.google.com/forum/#!category-topic/calendar/ios/jmqloVY4LmQ). I can't find anything to say why I'm having this issue or how to correct it. I've added it using all of the recommendations from Google, using a google account, and I've selected my calendars to sync. But It's not even showing my primary calendar now. Please help!

I had the same problem, but read this after the downgrade opportunity expired. After almost 2 months I figured it out. I set up the Gmail/Google Calendar/Google Contacts on my iPhone as an Exchange Account many years ago. Google discontinued this in 2013 for all new users, though it still worked for me (until Nov 17th). Google now uses CardDAV for Contacts and CaIDAV for Calendar (since 2013). They recommend using the Gmail app for their mail. Here is a link on how to set up Gmail/Contacts/Google Calendar: https://support.google.com/mail/answer/3008051?hl=en
I did this yesterday and now everything works. I was surprised that there weren't more complaints about the issue (I thought there must be hundreds of thousands of people affected) but most people probably have it set up using the newer method, which obviously wasn't affected by iOS 8.1.1

ICloud calendar not syncing to iPhone, iCloud calendar not syncing to iPhone

On my phone, I have a calendar called Calendar. On my Mac, and on iCloud.com, I have Work and Home. I cannot find an option to get the Work and Home sent out to the phone... any help?

I was having a similar problem where Calendar events I would add to my iPhone would not sync to my iPad or iCloud. What I realized is that in Calendar settings on my iPhone there is a calendar which is listed "On My iPhone" as simply "Calendar". That was where all my default events would go. Somehow, though, on my iPad and iCloud, only "Work" calendar entries seemed to sync.
Now I never really differentiated - I somehow stumbled into different calendars. This is the only way I figured out that "Work" was syncing across all levels. So this may not work for everyone who likes to separate Work and Home, but I edited my future events to change them to the "Work" calendar - and will make all entries in "Work" from now on - and now it all syncs.
Maybe there's another fix, but I think for my particular case - where most of my calendar entries are made on my iPhone - and were made in the default "Calendar" calendar, it works now.

ICal calendars not syncing with iPhone 4 running iOS 4.0.2

I have an iPhone 4 running iOS 4.0.2
I'm using iCal on my MBP running Mac OS 10.6.4
I have a MobileMe account.
Never had an issue with calendars syncing with the iPhone previously.
I am using MobileMe Calendar Beta. This now displays my calendars in iCal under my MobileMe account name (eg. [email protected]) rather than the 'On My Mac' section that it use to.
I have five separate calendars in iCal on the Mac all named appropriately (eg. Work, Personal etc.) and all that appears on the iPhone is one calendar named 'Calendar' with no events in it??
I've used MobileMe (.Mac) and iPhone syncing for years and have them set up as I always have.
Does anyone have the same issues? Does anyone have any constructive advise?
Thanks
Jeff

Address Book & Calendars not syncing to iPhone

here is yet another one.
I use the address book and iCal for contacts and calendering on my Mac and as the source for those services on my iPhone. Syncing has stopped after the last release of iTunes (8.1.1). I have tried all of the fixes suggested so far, like cleaning iSync cache, disabling and enabling syncing for contacts and calendars from within itunes with no success. There is no MobileMe services involved, and the host is a Mac.
The only solution that works is to select itunes>iPhone>info>advanced>replace info on this iphone.
Looks like there is a bug, or am I just missing something?

Have you tried resetting the sync history on your Mac, which is done with iSync preferences with the iSync application located in your Applications folder?

IPhone Calendar not syncing correctly with iCal since Lion-install

Since installing Lion, the calendar on my iPhone is not syncing correctly:
Events created on my iPhone don't show on my Mac
Events edited on my iPhone don't change on my Mac
Events that I created in iCal on my Mac, for test-purposes, and then deleted immediately, show up on the iPhone when syncing.
Syncing through iTunes (not MobileMe).
Using WeekCal on my iPone, but it seems that the same is the case with the "original" calendar-app.
No similar experience prior to Lion-install.
iPhone is iOS 4.3.4 -up to date
Any ideas? Does anybody know how to reset the sync, for instance?

Hi, my name is Lucas, i'm an Apple Certified Technitian.
Last couple of weeks i've installed OSX Lion in a few Macs.
But one of them drove me crazy!
I have a Late 2007 White Macbook and i installed OSX Lion last week. I also have an iPhone 4 (Factory Unlocked) that i also updated to IOS 4.3.5 ... no problems syncing between them
Then i did the same with a 13'' Unibody MacBook Pro and an iPhone 4 (not unlocked)... no problems neither
Yesterday i installed Lion on a Mid2010 15" MacBook Pro and updated another iPhone 4 (Factory Unlocked) to IOS 4.3.5 and when i tried to sync the iphone with iTunes 10.4 nothing happened.
I mean, nothing.. the iTunes started syncing and when it gets to sync the calendars it stayied there forever.
I left it for hours and nothing.
As i said i'm an ACT so i tried everything.
1- Remove Calendars from iPhone and syncing again
1- Repair Permittions
2- Reinstall iTunes
3- Reset iTunes and iCal Preferences and Caches
4- Backup iCal - erase ical content and generate a new iCal database
5- Reset Syncing Prefs and logs
6- Use DiskWarrior from an external OSX
7- Reset PRAM
Nothing worked.
I thought it could be some conflict with Microsoft Outlook and/or Exchange server since this Mac is the only one of the three macs i installed that uses Outlook Sync and Exchange server and it's the only one that gave me trouble.
But disableing it didn't worked neither.
THE SOLUTION
I Already solved this thing out. But i still don't understand the logic of all this... anyway, what y did is this:
1- turn off microsoft outlook sync with iCal (from outlook preferences)
2- Backed up iCals (Just in case)
3- Create a new Calendar Category (by default you have Work and Home... i created one called Test)
4- i Created a new task at that calendar
5- In iTunes uncheck the "Sync iCal" box and sync the iPhone
6- Check th "Sync iCal" box, then check the "sync the selected calendars" box
7- Check the "Test" calendar and sync the iPhone.
This worked so i started creating task in this Test Calendar both in iphone and mac, just to test it, Worked fine.
Then i selected all the other calendars (Home - Work - etc) and i turned on the outlook sync
Then i synced the iPhone and Voilà everything is working again.
Now i can create task in outlook calendar and when y sync the iphone it appears on it.
I don't know what the problem is... but this looks like the solution
HOpe it works for you!

Thank you.

So you have business contacts that were lost... do you not have these on a Database in some shape or form? Sounds like you need to invest in a RAID1 backup setup for your computer so you dont have this issue in the future.
As for repairing your problem, sounds like you are going to need to start from scratch at this point or if the data is still on your phone look into a program that can take the information from the phone onto iTunes.

IPhone calendar not syncing

Please help. I am at my wit's end. I cannot get my iPhone calendar to sync to icloud nor to my Mac. Sometimes some events from my phone sync, sometimes not. I cannot figure out how to get everything to go where it should. iCloud and iCal seem to be in sync. New events from my phone do not sync. I have searched every thread I can find on the subject, no help for me. I do not use Outlook nor google calendars. Just iPhone, iCal, and iCloud. I only started using iCloud because it seemed to be the answer to this problem when my phone stopped syncing to iCal. It still doesn't work. I have tried turning off all my calendars, signing out of iCloud in my Mac's System Preferences, changing how far back events on my phone will sync, all to no avail.

I had the same problem too with certain calendars not syncing. I deleted my MobileMe account from my iPhone and then added it back again. All my data including the calendars that were not syncing repopulated my iPhone in just a few minutes. Everything seems to be working fine now.

Avoid installing iTunes 11 if you are a Windows user. Calendars, etc will not sync with iPhone or iPad. Anyone have a fix?

After installing iTunes 11.0, Outlook Calendars, etc will not sync with iPhone or iPad. Anyone have a fix?

I'm also seeing weird sync issues since upgrading to iOS 7. The sync issues started when I first upgraded to iOS 7 so I suspect that iOS 7 is to blame and the other system differences aren't an issue (i.e. I also upgraded to Windows 8.1 but it never worked properly when I was on Windows 8). For me, the only way to "sync" all the smart playlists and music is to restore from backup and then the first sync seems to work. However, I haven't tried that recently (I tried it a month back or so and it worked then) because it is ridiculous to have to restore your phone just to sync things! Apple needs to fix the iOS 7 quality issues.

Why will my icloud calendar not sync between my iphone and calendar on Outlook PC?

Why will my icloud calendar not sync between my iphone and calendar on Outlook PC?

I think I may be having the same issue In a round about kind of way. Just got an iPhone4S ... everything worked great until today when I started tinkering with the settings in my new phone and noticed my cloud was getting full and I had two iPhone back ups on there at 4GB a piece. So.... I deleted the old back up of the iPhone4 and after that is when I started noticing issues. The cloud on my phone can no longer authenticate itself , unable to tell me when the last back up was, and will not perform a back up at all. Furthermore I am unable to download apps or updates on my iphone4S, they all sit in "waiting" status....
I also must say that I purchased an iPad 2 and still have my original ipad in the house and active. Both back ups are in the cloud and both devices work fine independently and can download apps and back up fine as well. I'm pretty sure this may be the culprit concerning this issue and I too have no idea how to fix it. Please Help!!!

New events on Outlook 2010 not syncing with Iphone and Ipad

I have gone through the nonsensical uninstall/reinstall every 5 restars. This time my new events or contacts on Outlook do not show on iPhone or Ipad. There is also a new confirguration where the Outlook does not separate the iCloud calendar from Outlook calendar but lists them all, then iCloud as a separate box at the bottom. I've tried dragging to that box with no success. I make about 50 appointments and reminders to my calendar each week and use all devices whether in the office or out. How dare Apple not fix this known issue.

I just looked at topic called "Outlook 2010 - Outlook does not sync with iPhone / iTunes and used the fix suggested in that string of posts. It appears to have worked!!! My happy camper.

ICal will not sync with iPhone

When I tried to sync an appointment created on the iPhone with iCal it will not show up in iCal.

I just posted this to an earlier question on an issue very similar. Might help some of you watching this topic.
This process, which AppleCare gave me last night worked to solve my problem. However, I have one nugget to add to the fix, a faster process to try first.
EDITED FROM PREVIOUS POST:
Try these steps to narrow down the offending calendar and/or event.
1. create a new calendar in ical. Name it test, iphone or something.
2. uncheck all your calendars in ical, so you can only view the events in the new calendar
3. put a test event in the new calendar ( in the future). Call it Test 1.
4. connect up your iphone and set the iphone to sync only to that new calendar.
5. In the info tab that shows up when the iphone is connected, make sure to sync ical calendars is checked
6. Set it to sync only selected calendars.
7. in the window that shows all the calendars, only have the new calendar checked.
8. put a check mark in the box not to sync items older than... Set it to 1 day.
9. Now click apply in the bottom right side of itunes. (this will see if the iphone can sync to ical)
10. Once you have established that the iphone can sync, go back into the info tab and uncheck the new calendar created and check only one of your old calendars.
11. Click apply and try to sync the iphone to that particular calendar.
12. Keep un-checking a calendar that syncs and check a different calendar until you run across a calendar that does not sync. The one that gives you a disconnect error.
13. Now that you've narrowed it down to the offending calendar, you know that it has to do with an event from yesterday and forward. (ED.- in my experience, this DID NOT prove that the event was limited to the time you specify for the sync. But it does no harm to narrow the scope for iPhone.)
14. Go back to ical and put a check mark in the calendar that is giving the issue. So now you see the new calendar created and the offending calendar.
15. Now you need to figure out which event/events that are causing the problem.
NEW STEP 16. Fast fix (try this first, and if it doesn't work, you'll try the longer piecemeal process.)
Cut and paste All events to your new test calendar. The fastest way do this is to open the list of events by clicking on the list icon (3 lines) on the bottom left of ical.
17. Sort by title and if any events show up with a blank title, fix these or delete them.
18. Sort by type of item so you only select the events, and not any ToDo items.
19. Shift click at the top of the list, shift-click at the bottom of the list and everything should be highlighted. Then, with the cursor on one of the items highlighted, Control-click and a menu will open. Select Calendar, and then your test calendar. This moves everything into your new calendar.
17. Try to sync.
In my experience, ical fixed some items that were queer by moving them to a new calendar. My original calendar was imported from Outlook.
If this doesn't work, you'll need to try again by creating another test calendar and then moving over a few items at at time, syncing after each import, wading through your events until you find the culprit.
We return to our regular programming here:
16. Start moving events over a few at a time to the newly created calendar and sync the iphone only to the new calendar. You can move events 2 ways.
16A. if you have the tray to the side expanded so you can view the details of the event, you can change what calendar it is in.
16B. At the bottom of ical there is a button to the right that allows you to view all evens in a list view. You can right-click or control-click on the event and move to a different calendar.
16c. CORRECTION TO ORIGINAL POST Sync iPhone.
17. Keep following step 16 until you receive the the disconnect error.
18. When you get the disconnect error again, you know that the last batch of events has the offending, or one of the offending, event/events.
If you run through all of your calendars and do not receive the disconnected error, then the data that was disconnecting the iphone was older data. (ed. -In my experience, this proved false. the error was buried in old data, even though I had the setting at "1" day.)

Icloud calendar not syncing

I've added appointments to my calendar on iMac and it doesn't sync on iPhone and iPad. Same with the address book. I will change info on one of my devices and it doesn't change on the others. I checked in System Preferences under iCloud, both calendar and address book are selected. Same with devices.
Any other things I should be doing? Or where can I find more troublehshooting tips. Thanks.

Contacts not syncing.
First check that all your settings are correct, that contact syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the contacts you are adding are added to your 'iCloud' group and not an 'On My Mac', 'On My Phone' or other non iCloud group (you can do this by checking in groups), non iCloud contacts will not sync.
If you are sure that everything is set up correctly and your contacts are in the iCloud group, you might try unchecking contact syncing in the iCloud settings, restarting your device and then re-enabling contact syncing.
Calendars not syncing.
First check that all your settings are correct, that calendar syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the calendars you are using are in your 'iCloud' account and not an 'On My Mac', 'On My Phone' or other non iCloud account (you can do this by clicking/tapping the calendar button in the top left corner of the application ), non iCloud calendars will not sync.
If you are sure that everything is set up correctly and your calendars are in the iCloud account, you might try unchecking calendar syncing in the iCloud settings, restarting your device and then re-enabling calendar syncing settings.
