I started this thread because of a difficulty with Zimbra an Lion iCal. My MM account works fine for me. But I no longer have need for it since my work uses Zimbra. However I did see an article that might be helpful you can find it here:
I hope this is helpful.
I did a lot of looking around over the last few weeks while I was trying to get Zimbra to work well with Lion iCal. Actually, it has been fun messing around with the settings etc.Mac OS X (10.7)

It seems you are a little better off than I am in the sense it is only when you create an event it will not sync. In my case iCal on my iMac will not sync. Occasionally after I have deleted the calendar and the account on the iMac and then add the MM account again it downloads the updated calendar on the first connection with MM. Thereafter it no longer syncs at all. My MacBook, iPhone and ipad sync fine.
Following advice here I located the hidden calendars folder in my user account and deleted all that was in it. I could not find any other references to calendars on the computer. Then cleared it out from the Trash. Have done this a few times. Yet when I go into iCal again to set up I notice that the day settings are always there, these are not the default ones but what I had inputed where I set the start and finish times at 06:00 and 19:00 respectively. This indicates that even though I have deleted all the calendar data somewhere else on the computer some settings are being stored and it may be I need to get to that to delete to ensure I start completely afresh. No idea where to start to find such though.

Further update re iCal.
I have been in touch with Apple Support who tell me they know about this issue with iCal, there is nothing they can do about it at present but are looking into it. No idea when that "looking into" will translate into rectification.
I find it surprising that Lion could have been released with this problem as it is surely one that would have cropped up in the beta stages, indeed before the beta stages as its a fundamental aspect of the software. Apple accepts its a widespread issue.
It seems we have to wait - or go back to SL.

What a pain! I actually enjoy tinkering with my computer and trying different things or trying to discover a workaround for problems. However, when you discover that you can't get it done because the system is broken then that is really frustrating. Hopefully the fix will come soon. It is good to know that they are aware of the problem.Mac OS X (10.7)

Just an update: a co-worker recently received a new mac desktop. Coming straight out of the box with the latest Lion OS he had no difficulties whatsoever with his iCal syncing with his Zimbra Calendar or with his iPad. It worked smoothly from the get go. So the issue that I encountered with Lion iCal and Zimbra's Calendar seems to only be a problem for those of us who upgraded to Lion from Snow Leopard.Mac OS X (10.7)

Sorry but that is not the answer. I am running an iMac with Lion that has not been upgraded from SL. It was a fresh clean installation of Lion, done by my local Apple store, on a clean new hard drive which they installed......and still iCal does not work.
Having talked to Apple Support this is a known issue, they are working on it and if I understood him correctly its something to do with the new iCloud that is coming and its syncing properties. We just have to be patient and await the update to Lion 10.7.1!

That is tough, waiting for the update so I could get Zimbra to work was no fun. Hopefully the update will come out soon.Mac OS X (10.7)

Finally I fixed it. I had the same MobileMe calendar sync problem in Lion (10.7.1). iCal showed "Updating..." in the title bar and my MobileMe calendar in the list of calendars just kept cycling forever. Events created on the computer did not show up in MobileMe, iPhone, etc. Computer was slow, iCal using lots of CPU, etc.
1. After some reading on the support website I suspected corrupted events imported from airline / hotel / car rental websites, so I went through the calendar and deleted those.
2. Then I did File / Export ... and exported a .ics version of the problem MobileMe calendar to the desktop. I also did File / Export ... and made an iCal archive, just to be safe.
3. Then on me.com I deleted the problem MobileMe calendar (in the list of calendars on the left you press the edit button then delete). I also deleted the same calendar from iCal.
4. Then in iCal I did File / New Calendar and created a new calendar in the me.com section (not On My Mac or any other section---very important; that's the only way to load a calendar back up to me.com) with the same exact name as the one I had deleted. Then I did File / Import ... and imported the .ics file into iCal that I had earlier exported to the desktop. Doing this gave me several scary errors and it refused to import. I made sure the me.com calendar was gone and that I was fully logged out of me.com and not using Calendar on my iPhone, tried the import again and it worked. I do not know why. (note: I was always able to import the .ics file as a regular iCal calendar in the On My Mac section of iCal, but that isn't what I needed).
With the calendar back in iCal as my me.com calendar, it automatically started syncing with me.com. However, it was using tons of CPU, saying Updating... constantly, etc., as before. The difference was that after a few minutes, it would give me a server error message saying a particular event was not allowed, or something like that. All these events were ones I had been invited to by my wife, or that I had invited her to. These events clearly were causing problems before I did steps 1-4, but for some reason iCal / me.com had not been telling me about them. So I was getting closer to a solution.
5. Each time I got the error message, I pressed the Go Offline button, disinvited the invitees or deleted the event, then quit iCal, then relaunched it, and waited for the next error message. One by one I fixed or deleted all the bad events.
6. I also had my wife stop sharing her calendar with me, and I stopped sharing mine with her.
7. Also, as a precaution, I quit iCal, then in the Finder I did Go / Connect to Folder ... ~/Library, went to Preferences, and deleted all the com.apple.ical... preferences files showing there (3 or 4 of them). Then I relaunched iCal.
Finally, it said Updating... for about a second or two, then all was fixed. Now it no longer says Updating..., it's not using CPU, all my calendars on the iPhone and me.com are syncing perfectly with iCal, etc. I can't say for sure whether all of the above steps were necessary, but they worked.
PS. I have Zimbra calendars also in iCal, simply via a CalDAV account in iCal preferences. That has always worked perfectly and was not the source of this syncing problem. I do not use any Zimbra connector in System Prefs. That has not been necessary since Zimbra started supporting CalDAV. You should remove any Zimbra connector.

Wish I could cure my problem so easily. Not had any error messages when it tries to sync, it just says it can't on the iMac. No problem though on my MacBook, iPhone and iPad. Am hoping we will see this resolved in the next few days when iCloud is opened up to us and version 10.7.2 of Lion is released.

It seems like the upgrade to Lion 10.7.2 cured the problem with duplicated calendars for me. I'm keeping the fingers crossed as it's only one day without problems until now.
