Delete " On My iPhone" calendars? iPhone 3.0

You don't need to jailbreak your iPhone. All the tools you need for syncing are available on Windows just as they are for Mac (trust me, I would know)

spritemv, there are a few ways to solve your dilemma. Since the iPhone doesn't support the deletion of calendars from its UI (except for CalDAV and subscribed calendars since they're "accounts"), you'll need to find a way to replace the "On my iPhone" data. You can do this by either enabled a MobileMe account (You can create a trial account at http://www.apple.com/mobileme/) or create an empty calendar in Outlook, then in iTunes, use the "Sync only selected calendars" option, choosing your empty calendar. The secondary option won't remove the "On my iPhone" calendar group, but it will remove the existing data replacing it with an empty calendar.

If you use the MobileMe options, see my instructions (using Contacts as an example) in this thread: http://discussions.apple.com/thread.jspa?threadID=2048666&tstart=0

Thanks for the advice ibaj. I created a separate, blank Outlook calendar via the directions on . However, my the second calendar is not showing up in the sync panel of iTunes. Under "Selected calendars:" I still have only the original "Calendar" and not my new "Blank Calendar." I thought maybe I needed to add an event for it to show up in iTunes, but that did not work either. Is there something special I need to do for it to show up?

Generally, you need to restart iTunes when you make a change to the calendars (not events, just calendars) in Outlook. Let me know if that doesn't work...

Hmm.. I tried restarting iTunes, restarting Outlook, and restarting my entire computer all without success. The blank calendar shows up from within Outlook, but still isn't showing up in iTunes. Any other ideas?

Is your calendar "Blank Calendar" a sub-folder of "Calendar"? If it's not, then it won't be seen by iTunes.

Success! It was a separate folder before, but once I made it into a subfolder and restarted iTunes, it worked as planned. Thanks so much for your help! Hopefully others with the problem are able to work it out the same way!

I was having this problem, I not only had 2 calendars on my iphone despite only one on outlook, I could not clear the calendar even if I synced it with my blank outlook calendar (itunes still thinks outlook has 2 calendars eveb though I can only find one in outlook).

I set up a temporary mobile me account (may now make it permanent with the find my iphone feature) and, as described above, managed to delete all calendars on my iphone.

My work uses meeting maker which I am now going to try to sync, we'll see how that goes, in the meantime I will keep my mobile me calendar blank and turn off the mobile me syncing on order to preserve this option in the future.

Thanks to those who pointed out the mobile me solution, a little tedious to have to create an account but it only took about 10 minutes total.

I had a trial MobileMe account and did not renew it.

Now I cannot get rid of the "On My Mac" calendars after resetting the sync servcies and backing up from restore.

I have tried all the suggestions EXCEPT restoring from bare metal.

Help! I need a delete caledar button!!!

If you don't have a MobileMe account, then the only calendars your phone should have (after removing the MobileMe account) should be the calendars from your Mac. Are you wanting to remove all your calendars from your iPhone? Where do you expect to get your calendars from?

I have 2 calendars under "On My iPhone". One is a Google Calendar CalDav copy.

The other is an empty calendar I use to try to fix the problem.

I have an exchange account from work.

The other is a Google CalDav Calendar.

i want to remove the duplication of the "On My iPhone" version of the Google calendar and the CalDav version of the same calendar...

Interesting...the name has chnaged from "On My Mac" to "On My iPhone"

...and the calendar entries on the Google CalDav are deletable and the same entries duplicated in the "On My iPhone" version of the Google CalDav calendar "Name[account@gmailblahblah]" are not deletable...

When I try to add a calendar entry there is no option to add to the Name[account@gmailblahblah] version of the CalDav calendar as it does not appear in the calendars available under the On My iPhone list.

I used to have just one calendar on my iphone, it was a caldav account with google. Easy. Well I accidentally deleted it, and upon re adding it I now have "On My iPhone" and "google". I just want google. How do I delete the on my iphone calendar?

Thanks, sorted my problem out perfectly

After reading this thread, I decided to go exploring on my own and found a solution. I use iCal, and had deleted specific calendars on my Mac and found that they reappeared after syncing with my iPhone.

Solution:
With your phone connected to iTunes, select you iPhone under devices and go to the "Info" tab. At the very bottom of this page is an "Advanced" section. You can then choose to "Replace information on this iPhone:" --> Calendars. After selecting Calendars, sync your phone and your changes in iCal will take effect on your phone.
