One of Apple's more recent projects has been the upgrades to the MobileMe online services. Recently after a while of beta testing they released a sleek new Mail interface and navigation bar, and have also released new iDisk-related features for the iPhone. The latest revision is to the MobileMe calendar, and following its beta release Apple has made available a number of troubleshooting documents regarding the calendar.

As expected with any beta test, there will be known issues. Apple is keeping a log of these issues in this knowledgebase document, and will hopefully keep the page updated with the latest fixes and issues. Check in periodically if you use the calendar and are having troubles with some aspects of it.
This is the main go-to article for all information regarding the calendar beta. It contains information about what the calendar is, through to new features, supported browsers, how to join the beta, and other device and platform support. If you are curious about the beta but do not want to convert your MobileMe account to it just yet, then you might give this article a read.
This article covers problems that might arise when migrating your calendar data to the new beta calendar service. The article basically discusses reverting, removing unwanted items, resyncing with MobileMe and then trying teh upgrade again.
While calendars are backed up to Time Machine (if you use iCal) or synchronized with other devices, you may still wish to periodically back up your calendars manually, especially while beta testing the new calendar. This article discusses how to do this.
Eventually all MobileMe users will move to the new calendar, but if you are considering the jump into the beta, there are some preparatory steps to keep in mind. These include backing up iCal calendars, ensuring all calendar-supporting devices are synchronized, and even resetting all but one "master" calendar device (usually your main computer) before syncing.
Unlike the article that covers issues on the migration process for the new calendar, this one discusses fixes to various issues you may experience when running the new calendar beta. Keep in mind these are not the "Known Issues" either, since those do not yet have fixes.
This is a basic article discussing how to get calendars to appear in Outlook, even though they are not yet supported in Microsoft's email client.
