MobileMe account configuration not correct error on publishing calendars

Some iCal users have noticed a problem whereupon trying to publish their calendars to Apple's MobileMe service, they receive an error claiming the MobileMe configuration is not correct.

KiltedGreen:

"I try to publish [using iCal] it comes up with a dialog with the Subject above and says inside: 'Calendar could not be published. MobileMe member name is not correct. Publishing to PubSubErrors requires a properly configured NSBundle /Applications/iCal.app (loaded) account.'"

Despite this error, when users go to the MobileMe System Preferences pane the credentials seem to be accepted. Additionally users can access their iDisks, send and receive email, and otherwise use MobileMe perfectly fine.

For some, this happens with only with one or two calendars, but for others this affects all calendars. Users have had temporary success in resetting the sync data for the calendars, but this seems to result in the problem recurring.

There are several things users can try to correct this problem:

Fixes

Completely sign out of MobileMe Quit iCal and then in the MobileMe system preferences click the "Sign Out..." button and confirm signing out. Log back in to the account, and then in the "Sync" tab click the "Sync Now" button and ensure Calendars are checked.

Reset sync data In addition to logging out of MobileMe, users can try resetting the sync data on their computer, or on MobileMe. This is done in the "Sync" tab of the MobileMe system preferences by clicking the "Advanced" button. For the sync reset, choose "Calendars" from the drop-down menu instead of "All Data".
