Duplicate entries in ical on iPhone

Since upgrading to iOS 5 and OS 10.7.2 I have duplicate iCal entries on my iPhone, iPad and iPod Touch. I also had other iCal syncing problems but by deleting and replacing I think I've solved those.
On iCal entries that I've just now made on my iMac, they are synced correctly on my iPad and ipod Touch. However each of them are duplicated on my iPhone. I think the problem is that on my iPhone iCal app I have multiple calendars under "from my Mac" and also many of them repeated under "iCloud".
On my iPad and ipod Touch I only have the iCloud calendars.
My question is if I delete the "from my Mac" calendars from the iPhone will this eliminate the duplicates?
Will I do any harm by deleting those calendars? If I delete them can I get them back if needed?
Thanks for any help.

I'm having the same problems, I upgraded from Entourage 2008 to Outlook 2011 on my iMac running 10.6.8, and my Outlook/iCal/iPhone/iPad calendars are all different and I have duplicates everywhere, please HELP!!!

Deleting duplicate entries in iCal?

How do I delete duplicate entries in iCal (identical entries on the same date)?

Todd,
I suspected a more serious problem because the answer was too easy.
Thousands of duplicate entries...Is this what happened?
According to, Mac OS X 10.4: Stay away from the SyncServices folder: As if it were a swarm of bees, you should stay away from the SyncServices folder in Mac OS X 10.4. Removing or modifying anything in it—or in subfolders within it—may cause unexpected issues. (This folder is located in your Application Support folder, in your Library folder, in your Home folder.)
Deleting or modifying things in the SyncServices folder may cause unexpected results such as:
• Duplicate contacts in Address Book or appointments in iCal.
• Data loss in Address Book or iCal.
Important: Any lost or duplicate data could propagate to other devices and computers via iSync and .Mac sync. This means data could be lost on other computers.If that is your problem, I suspect that without a backup, duplicate entry deletion will at best be tedious, and at worst fraught with frustration. You may be better off starting from scratch.

Why do I get duplicate entries in iCal on my iTouch?

I get duplicate entries on the same day in ICal on my iTouch? Is there a way to remedy this problem?

Sound like you're syncing via iCloud AND via the iPod sync mechanism. Connect to iTunes and go to the Info tab. Uncheck the box:

Duplicate entries in iCal. I don't get it!

Is there some place that I can go to get a definitive explanation of how iCal, Mobile.me and Subscriptions are interconnected? I don't get it. I always seem to end up with duplicate entries in my calendar. If I remove a check mark in one calendar, then stuff disappears, but if I put the check mark back, then I end up with duplicate entries.
Seems to me that if I enter stuff only in iCal, then I should only see it once. Unfortunately, Mobile.me or subscribed calendars seem to cause things to appear more than once. Birthdays are a real problem. I enter them in contacts, but Mobile.me seems to want to pull them from there and from the calendar, then they show up twice. I don't understand what I'm doing wrong, and there doesn't seem to be any clear instruction (that I can find), clearly outlining where or how stuff should be entered. Maybe I'm just dense, but trying to sync between Mobile.me, my Mac, iPad, and iPod....is making me crazy.

JimminyC,
Try contacting Apple using Apple - Support - MobileMe.

Only receiving repeat entries in iCal on iPhone 3GS v5.1.1 since iMac went down for service

Yesterday I took my iMac in for service. Today I was checkingl entries in iCal in my iPhone 3GS v5.1.1 and all entries were missing except those that were Repeat entries. I tried to go to iCloud to check iCal but iCloud didn't recognize my account and password and said I had to creat a new account.
What is up?

I had this same exact issue while traveling in Italy and France (I returned yesterday 17-October).
Before leaving, I verified by phone w/At&T that I had all necessary features to use my phone overseas. They said yes I did have all necessary features to use my phone overseas. They did offer me their AT&T World Traveler plan for $5.99/month but I declined since I would not use this feature enough to justify the monthly cost. They said my phone would still work overseas, but my per minute usage rate would be slightly higher. ...HOWEVER, I could not connect with any of the available networks while overseas (same results/messages as you).
I just spoke w/At&T again. Now they say I did not have the necessary feature to use my phone overseas. This is what I found out:
1. You can sign up online for the World Traveler $5.99/month plan. This will allow you to use your phone overseas.
2. If you do not want the $5.99/month plan, you need to have the Expanded International Roaming feature activated on your phone. If it is activated, you will see it on your online account under "International Features". Be aware, the rates will be higher for all services (I believe they told to make sure "Data Roaming" is turned off, otherwise I will be charged $20.00/minute for internet access")
3. If you have had your phone less than 90 days, and you want to activate Expanded International Roaming, you must call AT&T and ask to speak with International customer service. According to my recent phone call with AT&T, this is the only department that can activate the services (@ less than 90 days).
I'm still not confident this issue is resolved, but I will find out next time I travel outside the United States.

Duplicates/extra entries in iCal on Iphone not ICloud related

So I have been having this issue for a long time and I have been through all the trouble shooting and it always points back to settings and whatever to iCloud. This is not an iCloud issue as I turned it off a while ago and I have Snow Leopard Version 10.6.8 on my Mac which I believe doesn't hook up to iCloud at all (Am I correct here?). I have an Iphone 5 and it is updated to the new IOS but this has been happening prior to the update and it ALSO happened on my previous iphone 4 and to my Ipad. I have finally deduced all the extra entries showing up on my phone are from any change I made to an entry on my iCal on my computer. For example: If I click on my Ical on my computer to make a new entry and deleted it, a new entry shows up on my iphone calendar for that event even though I deleted it from my computer. OR if I made a change to an event, it would show up on my iphone as two different events. The original way I entered the event and then another event on my phone with the change. (Same thing when I plug in my Ipad, makes all these crazy entried). I really need my calendar to work. This is ridiculous. Is anyone else having this issue or can someone PLEASE help me fix this???????

Hi kim standley,
Thanks for using Apple Support Communities. I would first try resetting SyncServices as described here:
Mac OS X: Resetting the SyncServices folder
http://support.apple.com/kb/TS1627
If the issue persists after that, I'd move on to this article:
Sync Services: Advanced troubleshooting for contact and calendar syncing

How do I get rid of duplicate entries in iCal on my mac after commencing iCloud?

I just got a new iPhone 4s, and have set up iCloud. I managed to sync everthing i think (ie. contacts + calenders) but now on my mac iCal I have three duplicate calender entries for one event, but only one entry on my iPhone. If I delete just one of the entries from the iCal on my mac (leaving 2 still there), the one calender entry on my iphone disappears. Please help. It is driving me mad!!

You don't want to get rid of, it's a security feature. If someone steals your Mac, all that account permits is Safari access, no other access to the computer. This enables you to locate your Mac.

Changes to contact information in iMac / MacBook Address Book results in duplicate entries only on the iPhone / iPad

I have my iCloud account synced to an iMac, MacBook, iPhone 4, and iPad 2. Any changes I make to a contact on the MacBook and iMac result in 2 different contacts on my iPhone with the same name.
In other words, making changes in the address book on my iMac or MacBook, adds another contact on my iPhone / iPad with the new information and same name. As an example, if I have "John Doe" as contact on all of my devices, and I decide to make a change on my MacBook or iMac, I suddenly have 2 entries on my iPhone as John Doe. They are not exact duplicates. 1 of the John Doe entries has my original information, and the other John Doe has my new information. Deleting the "old" John Doe contact deletes all of the entries on all of my devices and I lose all of my contact information completely on all of the devices for John Doe.
Making changes to a contact on my MacBook and iMac only causes issues with my iPhone / iPad. The synchronization between my iMac and MacBook work just fine, and a new entry with the same name is not created. My MacBook and iMac do not show duplicates so the "Look for Duplicates" function in my address book doesn't solve the problem on my iPhone. The only solution so far that seems to work is to go into the iCloud Settings on my iPhone / iPad, temporarily turn off my Contacts, thereby effectively deleting them, and then turning the Contacts back on. I did change my Apple ID email address recently so I wonder if that plays a role or not. My new Apple ID has been changed on all of my devices.
Hope that makes sense and hope some people out there have some ideas.

If you are using Outlook 2011, make sure you have the latest service pack and update.
Make sure your Mac Book and all devices have the latest update.
If the Calendar on the Mac Book is correct go to step 3
Assuming Mac Book Calendar is correct, remove accounts from iPhone, iPad.
Reconnect account to iPhone, iPad account.
All calendars should now be in sync.
There are times when the Mail, Calendar, Contact application has been corrupted (Outlook 2011, Mac Mail, Entourage, etc). This will cause all kinda of issues on your devices. You have to repair the mail client first. In the case of Outlook you can delete the profile and recreate it. In Mac Mail you can rebuild (from Tools on the menu bar)

Duplicate entries in ical

I have just downloaded iOS5 on my iPhone 4 and all my current iCal entries have been duplicated. Is there a way I can delete these, apart from going through them one by one (which could take many hours!)

In Calendar, click the "Calendars "button; delete the MobilMe calendar that's probably still syncing.
Worked for me...

How do I get rid of duplicate entries in iCal/iCloud?

Since switching to iCloud/Lion, every entry I make in iCal gets instantly duplicated. This happens on only one of two computers syced with iCloud. Help!

Yeah, everybody says that.

I notice the mail setting in iTunes is set to sync, but all the others are set at syncing with iCloud. What about mail? Should it be syncing with iCloud, iTunes, or both (I assume not both, but......). I still don't have mail working with iCloud anyway so I'm not sure what should be happening there.
I would be consistent with respect to the information in the "Info" pane in iTunes. That is, if you want to sync Calendars, Contacts, and email, use either iCloud for all 3 (e.g., enable all 3 in iCloud and deselect all 3 from iTunes) or iTunes for all 3 (select all 3 in iTunes and disable all 3 in iCloud).... don't break them up across services.

ICal has duplicate entries

Using:
Nano
iCal
iTunes to sync up everything (iCal, etc)
Issue:
Duplicate entries in iCal on nano but not in iCal on PowerBook
What I did:
I originally had it iCal set up with Sunday as first day of week. Everything in nano was just peachy. Then I had to go an fiddle with it and made Monday first day of week and now, when I sync, my every-two-week-on-a-Thursday event is showing up on Wed and Thurs. I changed the day of the week back to Sunday but no luck.
Any ideas?
thanks!

I live between two macs and export and import calendars from each to the other and I have the same problem. I too would like to know how to import without duplicating the same events?

Every time I sync my iCal computer with my iPhone 4 or iPad, duplicate entries are generated on both systems. What am I doing wrong or how can I avoid the duplications?

Every time I sync my iCal on my computer through iTunes with my iPhone 4 or iPad, duplicate entries are generated on both systems. What am I doing wrong or how can I avoid the duplications? I have been doing this for several years and this problem is a more recent issue, like in the last 6 months. I have been deleting the duplicate entries, on both systems, but some duplicates reappear through "general" entries that are connected to the correct color for a Calendar, but not the name. I am going nuts and wasting tons of hours trying to get the 3 calendars to sync without generating duplicate entries.

Choose one of the Calenders on ONE of the computers OR the MobileMe as the Master / correct account.
The REINITAILISE the data of MobileMe within preferences on the computer defining the datatransfer correctly (in the advanced box of preferences). The synchronise iphone contacts and calender directly on-line to MobileMe.
I posted a question on this today, and gave my own reply !

Why do I get duplicate events in iCal when I input them on my iPhone?

Every time I add a new event on my iPhone (as opposed to my iPad or desktop) I get a duplicate entry. This started to occur a few days ago for no apparent reason. This does not happen if I input the event on any other device.
Is there a way to solve this?
Thank you for the help!

This happened to me and finally figured out what the problem is I think. I have MobileMe syncing set up on my iPod Touch and also had set in iTunes to do syncing to the iPod Touch - so one set was coming from MobileMe and another was coming from iTunes on the Mac that the iPod Touch hooks up to.
So I turned off the Syncing in iTunes and now I only have one set of things on the iPod Touch.
I think the reason for this duplication is that even without MobileMe you can keep the Mac and the iPod/iPhone/iPad in sync - the problem seems to be when you do have MobileMe that you probably don't want to have devices be syncing to both MobileMe and to the Mac as well.
To disable the iTunes syncing go to the "Info" tab and deselect the checkboxes for "Sync Address Book Contacts", "Sync iCal Calenders" and "Sync Mail Accounts". Bookmarks can only be synced with MoblieMe since there is no option for this in iTunes. I also have checked the "Sync Notes" checkbox, but not sure if I should have this checked or not. I don't have two duplicate sets of Notes on any device, so for now am leaving this as is.
I think Apple should fix this problem as it seems like a common complaint.
Hope this helps...

Not all Mac entries on iCal appear on iPhone and iPad

All devices (iMac, iPhone, and iPad) have the latest operating systems and my Mobile Me account has been moved to iCloud. Up until recently (maybe the past two or three weeks), all iCal entries made on my Mac would sync with both my iPad and iPhone. Recently, none of the iCal entries made on my Mac sync with either of the other two devices. I also now have double entries for some future events (which I had cleaned up before somehow). Would appreciate help and advice on how to clear this up. Thanks

Ferd II, thanks for your input. It was quite instructive but it didn't solve my particular problem. I did find another post that finally solved the problem.
O Open System Preferences > iCloud
O Deselect Calendar box then reselect and restart Mac (I did choose the option of wiping out all of my calendar data)
O On the iPad tap Settings >iCloud
O Toggle Calendars off then back on then reset the iPad (hold ON/OFF & SLEEP/WAKE buttons until the Apple logo apprears.
A similar approach seemed to work with my iPhone but I still had several duplicate entries so I wiped all of them out and will reenter the data manually

ICal, Google Calendar, syncing problems and duplicate entries

Hi everyone:
I could use some help. Oy.
At work, we use Google calendar, and that hosts my appointments. I find the Google web-interface impossible, and would like to use iCal to access the data on the Google servers. I have no problem doing that with iOS--my iPhone and iPad manage to sync up fine, and syncing works in both directions; i can add and delete either on Google or on the iOS devices and everything is fine.
But on my desktop machine, I have problems of two sorts. First, once I follow the steps to add a calendar, the syncing seems broken; I can add and delete from the Google web interface, but nothing deleted from the desktop gets passed to Google. Second, I have many duplicate entries that show up on my desktop and some very old appointments that no longer should be on the calendar show up out of no where.
What I'd love to do is a full reboot, eliminating all calendar data everywhere (except on the Google servers, of course, where the work stuff is stored) and start from scratch. Any ideas?
Thanks in advance--
Roger

Have you tried rebooted your Mac? (Not needed often, so we Mac users often forget to try this. ) Are you logged on with an admin account or a standard account? (Or one with Parental Controls enabled.)
Sometimes I'll find the dialog window "behind" my other windows. Try not to click or move your mouse after you click the plus button. Or try moving windows around or minimizing them so that any windows that are hidden behind other windows are then shown. (In fact try closing all apps and Finder windows to reduce the possibility of this issue in the first place.)
(BTW, your question really is separate from the original question, since the OP already has their Google account added to iCal and you are having trouble adding the account. In the future you'll want to start your own thread so that you can also mark posts answered or helpful.)
