MobileMe: Troubleshooting MobileMe Calendar issues

Note: For instructions on setting up the MobileMe Calendar with iCal, see MobileMe: Setting up iCal for the MobileMe Calendar.

If you are having trouble with a Mac and syncing with the MobileMe Calendar, try each of these steps, testing after each to see if the issue is resolved:

• Make sure you are running Mac OS X v10.6.4 or later and that your MobileMe member name is entered into System Preferences. See this page about setting up MobileMe on a Mac for more information.
  • If using Mac OS X v10.5, see this article.
• Make sure your account was successfully created in iCal. After upgrading to the MobileMe Calendar, you may need to quit and reopen iCal. To confirm your account is configured correctly in iCal:
  • Open iCal.
  • Open iCal Preferences.
  • Click Accounts. You should see an account with your MobileMe member name entered.
• Restart your computer. This may sound simple, but it does reinitialize your network and application settings and can frequently resolve issues.
• Delete and re-enter your CalDAV settings for MobileMe Calendar on your Mac.
  • To set up your account manually in iCal on Mac OS X v10.6.4:
    
    1. Delete your account from iCal.
    2. Quit iCal.
    3. In the Finder, choose Applications from the Go menu. Open the Utilities folder located in the Applications folder, and then open Terminal.
    4. Paste the following lines into the Terminal window, pressing Return after each:
       • defaults delete com.apple.iCal UserHasRemovedMobileMeCalDAVAccount
       • defaults delete com.apple.iCal CalMobileMeMigrationToCalDAVRequestUpgradeAfterDowngrade
    5. Quit Terminal and open iCal.

• Make sure there are not any current issues listed in the System Status affecting the MobileMe Calendar listed at the MobileMe Support webpage. 
• Make sure the issue you are seeing is not covered in the Help menu already. To access help, visit me.com/help.
• Check your settings and preferences as something may not be set up correctly. For example, having an incorrect time zone setting can cause issues which are easily resolved by entering the appropriate time.
  

• If you're having trouble with the web-based MobileMe Calendar at me.com/calendar, the first place to start troubleshooting is your browser. This article details how to troubleshoot browser issues for a variety of web browsers for multiple operating systems. Browser troubleshooting should never be skipped for web-based issues.
• If you encounter an issue while using the MobileMe Calendar on the web, a message may appear with a "Send to Apple" button. Clicking this helps MobileMe to track issues and create fixes.

If you are having trouble with an iOS device (iPhone, iPad, or iPod touch) and syncing with the MobileMe Calendar, try each of these steps, testing after each to see if the issue is resolved:

• iPad: If you encounter any duplicate data after updating to iOS 4.2, see this article.

• Quit and restart the Calendar app on your iOS device:

• Change the Sync settings for your calendars:
  • Tap Settings and select Mail, Contacts, Calendars.
  • Scroll down to the bottom.
  • Under Sync, if it's set to All Events, set to a specific duration. If it's set to a specific duration, set to All Events.
  • Wait several minutes and try syncing again.
