Added calendar in iCal not synced to MobileMe

Question

I moved a calendar from "On My Mac" to my MobileMe account group, using the export-import method. The new calendar, however, does not sync to MobileMe. I even tried an overwrite (bookmarks, calendars, contacts and keychains) from my Mac to MobileMe but the added calendar still did not appear in MobileMe.
I quit and relaunched iCal, which started an immediate sync. The new calendar promptly disappeared from iCal and I got a string of error messages (one for each entry in the new calendar, it seems) all ending with
The server responded with
“HTTP/1.1 409 Conflict”
and asking me to either "Go Offline" or "Revert to Server". It didn't seem to matter which one I selected – the error just kept cropping up. Eventually, I gave up and force quit iCal.
How can I add a new calendar to iCal that will sync with MobileMe?

Answer 1

Derek,
I presume that this procedure represents exactly what you have tried to accomplish?
Import an iCal calendar or event
If you use iCal and want to add your iCal calendars and events to a MobileMe calendar, you can import them.

To import an iCal calendar:
Open iCal, and then select the iCal calendar you want to import into your MobileMe calendar.
Choose File > Export > Export.
Type a calendar name, choose a location from the Where pop-up menu, and click OK.You can store the exported file anywhere, and you can delete it after you finish importing it.
Choose File > New Calendar, and then choose a MobileMe calendar (by default, your MobileMe email address).
Type a calendar name (you can use the same name as the calendar you just exported), and press Return.
Choose File > Import > Import, select your exported iCal calendar, and then click Import.
Select the destination MobileMe calendar to which you want to add the imported iCal calendar, and then click OK.
Quit iCal and go to the Macintosh HD/Users/yourusername/Library/Calendars Folder and delete any/all files with "Cache" as a part of the name. Log out/in or restart and reattempt using the exact procedure which I copied from the MobileMe Help page.
