iCal calendars won't delete, keep coming back

Have the exact same problem

Same thing here.
I tried to complete reset ical so I could try to start fresh in order to (hopefully) solve syncing issues with mobile me.
I deleted all my calendars. I cleaned out cache files, library files and what else iCal related files I could find on my system.
Did a restart, opened iCal and voilá, there was a bunch of old calendars and entries back in there - don't have the slightest idea where all the old data is coming from.. drives me nuts!

I had to delete all my calendars months ago because of syncing errors. i have all new calendars and everything has worked great until this morning when apple resurrected 15 old deleted calendars on me.com. All of a sudden all of those old calendars were back, my phone and all three of my computers. I had to delete and force resyncs and everything. I imagine they did some sort of restore.

I deleted all of my calendars, the cache, etc., and when I started up iCal all of my calendars including long ago deleted calendars were there. That would be great except that I tried to pare things down so that I could try to get the iCal and synch services working. Where do the old calendars come back from? I have to wonder if there is an internal cache in the program folder itself.

Anybody have any thoughts?

I am having this problem as well. I delete a calendar and then for some reason it shows up again on MobileMe. I've reset the sync data so that it comes from my computer that does not have that calendar, but then that thing keeps showing up again. No one has any solution to this problem??

I'm having the same issue... Keep trying to delete an old Entourage calendar (gone back to using Mail, Address Book & iCal as Entourage was too buggy). But I can't seem to delete the old Entourage calendar. I even tried renaming it but the old "Entourage" name keeps reappearing! Any ideas??!?!?

Bump

I have the same thing, cleared the ~/Library/Calendars folder, emptied the trash, opened iCal and whoppa, all the calendars are still there. Even when I delete the calendars using Edit -> Delete, they won't go away. Trying to do all this due to MobileMe synching problems. But if I can't even delete calendars, my hopes of trying to solve this issue are diminishing quickly.

Ah well, what else to do on a Sunday morning, but to fight with iCal?

Found the answer in another, unrelated post: I had to clear ~/Library/Application Support/SyncServices.

Same thing here. Can't delete calendars. They keep coming back. But I don't have ~/Library/Application Support/Sync Services on Macintosh HD. In my user there is ~/Library/Sync Services but that only has ~/Schemas/MicrosoftOfficeNotes.syncschema

So, I am no wiser about this @£$%^&!! problem. Comforting to see others also have the same?

Thanks to John Maisey ( http://www.nhoj.co.uk/) I was pointed in the right direction.

1) close iCal

2) delete calendar cache
~users/[your user]/Library/Calendars/Calendar Cache

3) delete Events directory
~users/[your user]/Library/Calendars/*.calendar/Events

4) reset sync history (thanks John!)

5) open iCal

All gone!

Still expecting dawn of the dead, but living in hope.

Here's what worked for me:

1. Open iCal and delete every calendar you don't want anymore
2. Export an iCal backup (file-->back up iCal)
3. Quit iCal, Mail and AddressBook (if they're running)
4. Clear out the following folders (delete everything in them!) and empty the trash


/users/*YOUR USER*/Library/Calendars

/users/*YOUR USER*/Library/Application Support/iCal

/users/*YOUR USER*/Library/Application Support/SyncServices


4. Restart iCal
5. Restore iCal from its back up (file-->restore iCal)


After doing this, I no longer had zombie calendars appearing on my iPhone or in iCal!
