ICal duplicating events

My ipod touch iCal duplicates events. Even after I've deleted them they come back. I sometimes have six or seven of the same event in a day. I'm just about to give up and stop using it and try another app. This seems to be an old problem. I've found instances on here dating back to 2009. Haven't they fixed it yet?? Any ideas?

Hi,
Are the events in the same calendar or different ones? You can check this by showing and hiding calendars.
Best wishes

Duplicated events on iCal, and even more on iPod calendar

I am using the latest version of Mac OS X Lion and an iPod Touch 2G with the latest compatible iOS update (4.2.1)
I gave iCloud a try, but after syncing with my iPod, I wouldn't be able to create or edit events in my iCloud calendars (which were previously the "On My Mac" Calendars)
I decided to stop syncing iCal with iCloud so that I would be using "On My Mac" calendars that could be modified on my iPod.
I exported each calendar. Stopped syncing with iCloud (which deletes those calendars from my mac) and then imported them within new calendars that were named and organized as I previously had.
However, I started seeing duplicate or multiple event entries on my Mac and on the iPod Touch.
I tried to delete the duplicates from the Mac, and some of them delete, some don't.
It is weird because I have duplicates of the Address Book Birthday calendar too, which shouldn't have duplicated events that cannot be deleted.
Another thing that happens is that in iCal there are events that appear correctly, just one time. But checking on my iPod, I see the same event 7 times!
Please, somebody help and guide me. I am a heavy user of the calendar on both devices and need a fix soon.
Thanks!

I have the exact same problem.
Can't figure it out.
It is very annoying and time consuming deleting the duplicate items.

Duplicated events on iCal after moving to iCloud

Hi, i just updated mi iphone 4 to iOS5, then updated iTunes, then updated OSX Lion to 10.7.2, then moved to icloud...
Everything seems to be ok, but there's a problem: my events duplicated on iCal in my macbookpro...
Every input has cloned itself!
But, when checking on icloud and on my iphone, no duplicates!
So... what should i do?, 'cause if i delete a duplicated event from iCal in my computer, leaving only one, the event erases at all in iCloud and in my iPhone...
Weird.
Any suggestions?
I appreciate your time, thank you!

Hi Jorge. I just went through this entire process. I was able to rid myself of duplicates, however, I am still trying to figure out how to match a hard copy to my Mac without creating duplicates.
- Make sure you have your events on the Mac
- Go to iCloud on phone and turn off iCloud on everything (for now). It will tell you it will delete everything off iCloud (this is fine if you have everything you need on your Mac).
- Go into iTunes on Mac and "turn of Sync with this iPhone over Wi-fi" & check "back up to this computer"
-Go to info tab in iTunes on Mac. Check sync "contacts" & sync "calendars"
- While you are in the info tab also check "calendars" & "contacts" in the Replace Information on This iPhone section under Advanced.
- Synch
- If everything matches up properly go back to iPhone and turn iCloud back on for what you want
- Go to iCal on Mac and in the top left hand corner there is a "calendar" button that when you click it, it shows calendars for "On my Mac" and "iCloud".
- You can delete the "On my Mac" calendars to rid yourself of the duplicates.
***This is how I did it. You may be able to just delete the "On my Mac" calendars but I am not sure if that will take them off of iCloud and your iPhone. You can give it a try first as it may be less time consuming.
So, my issue is still trying to figure out how to keep matching calendars as a backup on Mac without the duplicates. Any takers?

ICal randomly duplicating events

iCal randomly duplicated events (sometimes twice, other 3 times) after the last sync of my iPhone. I've had, & continue to have this problem with repeating holidays which were transfered from my Palm but now I've got countless duplicate "normal" events over at least the last 6 months. In the past iCal has duped events & simultaneously change the dupe's time slightly but this time they are direct copies. I just finished correcting them manually. For future problems is there any way to automatically remove duplicates? More importantly, is there anything I can do to prevent this from happening?

Hi John,
Thanks for the information, sorry for the delay in my response -went out of town for a few days. iCal Dupe Deleter sounds seems to be just what the doctor ordered to remedy this situation next time it occurs.
As to my second question, do you, or anyone out there know why this happens or how to avoid it in the future?

ICal Duplicating Subscription Calendar

I am a MobileMe subscriber and have been having quite a problem with a subscription calendar. Every time I open iCal on my computer it is duplicating events from the subscription calendar hundreds of times, additionally it shows a new subscription calendar to the point where there are currently 204 subscriptions to the same calendar. I have unsubscribed to the calendar (no help). Deleted the extra subscriptions, attempted to resubscribe all to no avail. I believe this all started when I attempted to sync Google Calendars with my iPhone (just a theory). It has gotten to the point where I had to turn off calendar syncing on my iPhone because the calendar issues were causing it to be slow to the point that it was unusable. So now on to the questions:
Has anyone ever had this issue?
Is there a way to bulk delete events (same day/time)?
Can this be fixed without a complete deletion and recreation of my MobileMe calendar?
Any thoughts and suggestions would be appreciated.

A tech from mobileme should be able to help you with this with no problem. You can either chat with them or have them call you on the phone. I think you are going to have to go into advanced mode and reset syncing for the calendars.

Ical - deleted events prevent from syncing with missing sync

When I try to sync ical with my windows mobile 5.0 running Motorola Q via Missing Sync, I always encounter an error message that one of my ical-events prevents Missing Sync from an error-free sync.
This message comes up when I start Missing Sync: "iCal is reporting synchronization errors. One or more calendar events may not have synchronized properly from iCal. Errors may prevent this application from completing a successful synchronization."
The Missing Sync Protocoll rerfers to an event which I did already delete. So here's the question: how do I really get rid of a ical event which I have already deleted?

Same here. After the update to 10.5 I have succesfully done one sync between my Treo and iCal using MissingSync. Now iCal gives an error, see below. What is the workaround? Downgrading to 10.4.x? Or get an iCal 2 somewhere and run that?
I really want to get my ToDo and Calendar data from my Treo before I go from my Treo 650 to an iPhone. Any workaround is welcome.

My calendar keeps duplicating events.

My calendar keeps duplicating events. I noticed it happened after I turned the iCloud calendar back on. It ask me to merge events. Help anyone?

You get duplicates, one from iCloud and another when you sync with your computer, IF iTunes is set to sync from the computer to the iPhone. Check your device settings (general tab, IIRC) in iTunes.

Duplicated events

My manager emailed me our work schedule and since we have tons of duplicated events, it is being rejected by icloud. How do I allow the duplicates to stay?

Open the calendar application on your Mac and create a new iCloud calendar with an appropriate name (such as Work Schedule) by going to Calendar>New Calendar>iCloud. Then import the .ics file to the new calendar by going to File>Import>Import, navigate to your .ics file. When prompted to choose where to import it. click the drop-down menu and select the new iCloud calendar you just created and Import. Wait until the rotating wheel at the top of the left sidebar disappears and you new calendar should appear in iCloud.
You shouldn't encounter any duplicate event errors because you are importing it into a separate calendar.

Syncing iCal reccuring events created before DST

I have a problem with my iCal reccuring events created before the transition to Daylight Saving Time. On my iPod nano they appears to stay as if they were still before DST shift (in non-DST time zone). For instance, if I have a weekly meeting at friday 5:00 PM, I expect it to be 5:00 PM independently of whether I'm in a DST-shifted time or not. On my iCal everything seems to be fine: the meeting is still 5:00 PM, but my iPod nano thinks that the reccuring meeting should be DST-independent (6:00 PM).
Temp workaround: Settings > Date & Time > Set Time Zone > Set a time zone without DST. However, after syncing, the timezone will be resetted to DST anyway.
Hope this issue will be fixed in future iPod software releases.

I am having the same or a similar problem.
I use iCal on Snow Leopord and can't seem to get calendar events to sync when created in iCal with my BB or those created on the BB to show in iCal.
I use gmail, and have gmail added as the only account in iCal.
When I connect my BB via USB, Desktop Manager indicates that one of the selected calendars is read-only and can only be synchronized from my computer to my device. How do I correct this?

N97 iCal iSync Duplicating events

Hello All,
1st post for me on here! I have had a look on the both iSync & iCal discussions but couldn't find an answer to help me so i'll post my question, small problem so hope someone can answer.
I got my iCal & address book on my Mac all nice & tidy then sync'd it to my N97 (which was new so nothing on it). After the Sync, my contacts & calendar on my N97 were looking great, the following day when I sync'd again to update a few new contacts the calendar on my N97 & the iCal on the Mac have duplicated every event! I can see all the original events but the duplicates are all there in one colour no matter what they represent (i.e. birthdays, work, etc). Is there a straight forward way in removing the duplicates & stop it from happening again?
I've tried a 3rd party app but it couldn't see the duplicates!
Many thanks for any help.

Hi,
I have just had a similar problem. I am not sure if it applies to you but hey here we go...
Basically i have 5 tabs on my ical calender i.e red, blue, green etc for three different buildings i manage. Now heres the crucial bit, when isync adds to the phone for the first time it only puts the events on the phone in one colour ( in my case the blue tab) so when you sync for the second time the ical calender sees all these blue events and thinks they are new events and duplicates! once you have removed the duplicates the problem should resolve...
Cheers. Hope this has helped.

Duplicated events on iCal after .mac sync

Thre facts:
I have a TREO600, a desktop mac, and a powerbook, both running Tiger 10.4.4.
Due to some other problems with syncing the TREO, I have purchased the Missing Sync from MarkSpace, and that works very well to sync the palm with the desktop.
I started syncing my two computers with .mac lately, and I have nothing but trouble. Nearly every sync throws up some conflicts, often about events that have long passed. I went through the long list of conflicts EVERY time this happens, but iSync seems to complain about new conflict nearly everytime I sync.
Moreover, it seems to duplicate certain (but not all) events on my iCal after it has synced with .mac.
This is super annoying. I have seen that there are many different posts on duplication already, but none of them seem to match my problem, though there definetly seems to be a general problem with iSync not being very good at checking for duplicates.
Any ideas how to solve this?
thanks,
marc

Because you are running the Missing Sync for Palm OS in a Mac OS X 10.4 or later environment, the synchronization of your data is a separate process controlled by .Mac Sync. In order to correct the issue, you should perform a reset, replacing all of the records on .Mac with the records from iCal and the Address Book, which should, incidently, be contemporaneous with your Treo 600 smartphone.
To do that, launch System Preferences and select the .Mac pane. Press the Advanced tab, then the Reset Sync Data… button in the lower left corner of the dialog box. Reserve the default directional data transfer from .Mac to your machine by pressing the right-facing arrow beneath the .Mac icon. This will shift directional flow so that data moves from your computer to the .Mac servers. You can keep the Replace: All Sync Data value in the drop-down menu above, or choose to synchronize only one data type [Calendars or Contacts] by selecting the appropriate value. If you synchronize them separately, you must repeat this process for the other data type.
This event will transfer a complete set of records from iCal and the Address Book to the appropriate storage locations on the .Mac servers, replacing the non-matching data currently stored there. It will not affect your continued use of the Mark/Space Contacts, Events and Tasks menu, and will not change the data stored on your handheld the next time you synchronize.

ICal duplicating All Day events.

I sync my iPhone via USB (not iCloud) with my Mac.
Every now and then if I go through my historical iCal entries, I've noticed that quite a few All Day Events have replicated itself. Some twice whilst others can be replicated up to ten times or more.
This raises the need to indulge in a 'new hobby' of scanning iCal regularly to remove the duplicates manually. In spite of this, iCal persists to replicate some All Day events.
There doesn't appear to be a definite pattern to its replication because it replicates All Day events from more than one Calendar and does so on every other All Day event resulting in what appears to be a randomised replication.
I have no plugins or third party apps which integrate to iCal. For all intents and purposes (to my knowledge) my iCal is stock standard.
Does anyone know what causes this and how to stop it once and for all?
Thanks in advance!!

Try opening isync from your applications folder.
When isync opens, open the isync preferences.
In the isync preferences, click the button to reset sync history.
Once the sync history is reset, quit isync and try syncing the iphone again.
If this does not work, go into the entourage preferences and stop entourage from syncing with ical.
Export all events from ical and clear out any calendars.
Now create a new event in ical and try syncing just that event to the iphone.
If that event syncs ok, go back into the entourage preferences and enable syncing with ical again.
Now try syncing with the iphone.
Hope this helps.

ICal duplicating entered events multiple times.

After trying to sync my calender with the calender cloud app. multiple copies of each event appeared. Where did I go wrong?

Hi,
More information would be useful.
What version of iCal are you using?
Have you synced your calendars previously? If so have you turned that syncing method off?
Are the events in different calendars? Do you have duplicate calendars under the "On My Mac" and "iCloud" section of iCal?
Best wishes

ICal creates calendar account every time I open iCal - duplicate Events

Hi,
I have a Lion Server and 2 Clients (with Lion). All the latest updates are installed on all computers.
On the Lion Server is the iCal Server running.
Ok I configured iCal on a client (Lion). This client has 2 cal accounts (in Preferences -> Accounts).
Nr.1 = WebDAV from the Lion iCal Server
Nr.2 = the iCloud accout from the client-user
Ok here is my problem:
When I start iCal on the client mac, iCal everytime creates a duplicate iCal account of my WebDAV account. So the account Nr. 1 exists twice AND all events will be duplicated. If i wouldn't delete the new account everytime, the WebDAV-account would exist 10 times (when I start the app 10 times).
And this account will also be created when I delete ALL accounts in iCal and restart the app. This also happens when I deactivate the iCloud account on this Mac.
I also tried to delete all files in ~/Library/Calendars but this problem still exists!
This is really annoying.

Ok, the same problem occurs when I start my mac not in my local network, but in a network that is connected to the Internet. The WebDAV cal account will be created automatically when Internet is available.
Any suggestions?
