how to delete a calendar on the iphone ???

Try deleting your MobileMe account from the iPhone, then re-adding it.

Before deleting the whole account, try just stopping the calendar syncing in the MobileMe account on the iPhone.

Go to Settings>Mail, Contacts, Calendars>Your MobileMe account.
Set Calendar Sync to Off.

Wait a few seconds, then turn it back on again.

I have the same problem, but syncing on a PC with MS Outlook. How can I get rid of the second calendar?

Did you follow the instructions included with the previous post in this thread?

Thanks. However, I don't use MobileMe. I sync on my PC desktop via iTunes.

The second calendar was accidentally created when I imported a new .pst file into Outlook 2003. I have now deleted this second calendar in Outlook, but it will not disappear from my phone or from iTunes.

In the meantime things have gotten worse. I am now getting a message during iTunes on startup that syncing on this computer has been turned off. When I say "yes" to enable syncing, I get error message "iTunes was unable to load provider data from Sync Services. Reconnect and try again later." In iTunes I can no longer check the boxes to "sync contacts with" or "sync calendars with" ... Outlook does not appear any longer as a choice.

Any idea what is happening here and how to repair?

You're welcome. However, you don't have the same problem as the original poster for this thread who does have a MobileMe account.

You should start your own thread with the deatils about your problem since you don't have a MobileMe account.

Actually, this is the same problem but with different circumstances. The behavior is actually independent of Mobile Me. I have this problem too, both with Mobile Me and locally synced calendars.

Deleting and re-adding the Mobile Me account does not fix it.

Short of resetting my phone, is there any solution to this??

I finally worked this out. My situation had old calendars that used to be synced in combination with switching to a different Mobile Me account.

Bottom line is that once a calendar is created locally on your iPhone for whatever reason, there is no way to delete it. You can only reconfigure the set of calendars, but how to do that can be a can't-get-there-from-here-in-this-state problem.

Here is a step by step of what I had to do to restore sanity:

This assumes there is no calendar information that lives only on your iPhone that you want to keep.

On your iPhone, in Settings->Mail, Contacts, Calendars, find your Mobile Me account, turn off "Calendars". Exit the settings application (hit the button to go back to the home screen), or the next sync will fail.

Temporarily create a calendar in iCal called "Apple FAIL" or something. In iTunes under your phone->Info, "Sync iCal calendars", select just that calendar (unchecking the option to sync iCal calendars won't clear out the stranded ones).

Under "Advanced" on the same screen (you might have to scroll down to see it), check "Calendar" under "Replace information on this iPhone"

Sync.

On iTunes, uncheck "Sync iCal calendars"

Sync.

On your Mac, delete the temporary "Apple FAIL" calendar you created

If you are using Mobile Me:

On your iPhone, go back to Settings->Mail, Contacts, Calendars, find your Mobile Me account, turn "Calendars" back on.

Otherwise:

In iTunes, select the iCal calendars you want and re-sync

Soapbox:

Apple is normally good at solving complex issues with an intuitive user interface and a convenient workflow. This situation is a fail on both accounts.

What lead to this situation for me is I wanted to see subscribed calendars on my iPhone in addition to using Mobile Me. Syncing a subscribed calendar in iCal from my Mac won't actually set it up on my iPhone as a subscribed calendar, so that calendar on my iPhone is only as up-to-date as my iCal version of it was as of the last time I synced, which then will only be as up-to-date as the last time I ran iCal and synced it. Instead, I have to manually subscribe to the calendars on my iPhone by either emailing myself the webcal: links or typing them into Safari on my iPhone. Managing subscribed calendars both on my iPhone and iCal is a giant PITA.

Thank you this worked like magic.
I used to the same idea to remove the duplicate contacts as well.

The only extra thing I did was to turn off automatic MobileMe syncing during the process, just to make sure that it didn't muck things up half way through.

I agree with Apple pushing MobileMe so much it would have been nice if they had prevented this error occurring.
Thanks again, I was going crazy.

Had same problem, except with Outlook instead of iCal, and Exchange instead of MobileMe. This process worked. Not sure I really needed to turn off Exchange sync and then re-enable it at the end, but it didn't seem to hurt.

Apple, get it together! Add an option to remove calendars.

Paul,

Your procedure worked perfectly. Thank you very much.

Brilliant solution. Thanks.

Worked perfectly. I now have only the mobile me calendars.
I also figured, that if you use the subscription feature, you can also display Birthdays simultanously with your Mobile me calendar on your iphone by using all calendars. I did not use that option prior becasue I had duplicates, but your procedure made it all possible, many many thanks.

To use birthdays, go to preferences, in general tab in iCal click show birthdays. Then close the preference screen, richtclick (ctrl-click) on the subscription Calendar birthday and publish. then click rightclick again and select copy url-to clipboard.
Go to mail and write yourself an email with pastin the adress into it, and send it to your mobile me. In Iphone open the mail you sent yourself, and click the link...and wait a bit. I am not sure if it just takes a while or if you need to exit the mail until a small window asks you if you want to subscribe. Mine showed after I waited and then exit the mail.
Now it is on the phone too, and using all calendars also displays the birthdays simultaneously with the mobile me calendars.

But maybe ya'll already knew this, but anyways...thanks again 🙂

I'm having the same problem - had caldav account and it was the only calendar on my phone. Deleted it by accident, re added it, and now i have two calendars: "On My iPhone" and "Google". How do I go back to only having my caldav calendar, and not "On My iPhone"?

Thank you so much for this post. More complicated than I would have hoped but your suggestion worked. Would be nice if Apple would make the Exchange integration work a little simpler & more consistently
