ICal still does not sync with exchange 2007 in Lion

Question

Dear,
In Snow Leopard, iCal was not syncing with Exchange 2007. I read a lot of things on this and it all led to recurring events. Indeed, after deleting them, things started to work. But I cannot delete recurring events! I need them!
Seeing that there was soo much talk on this all over on apple, I assumed that Apple would fix it. Instead, all we're seeing is some enhanced UI.
Can somebody at Apple please make sure that this thing finally gets fixed? Really, how hard can it be, knowing that the hardware based i devices can sync without any trouble?
Just for extra information, so you know what direction to look for:
I have Windows SBS 2008 in Dutch language. Timezone is Brussels. Exchange 2007 and all updates.
The system is running a self signed certificate
Outlook works fine on the Mac. I don't want to use Outlook on the Mac but am forced to at the moment.
Mail/Addressbook sync fine. Only Outlook doesn't!
I did try deleting recurrent events and this worked for a day. Basically stopped working I think when I added again those recurring events.
There are some errors in the console:
21/07/11 11:42:36,563 iCal: Couldn't find an NSTimeZone to match the SerializableTimeZone
21/07/11 11:42:36,563 iCal: WARNING: Failed to find TimeZone Identifier for Windows MeetingTimeZone: (GMT+01:00) Amsterdam, Berlijn, Bern, Rome, Stockholm, Wenen

Please fix this,
Guido

Hi all,
I do have exactly the same problem.
But I am adding a new flavor, but I can not understand it.
I've setup two Exchange calender connections. Both servers are inhouse. The setup of the Exchange servers are most likely the same.
But one works and one not! How could this be explained?
I like to express my deep disappointment about iCal and partly Apple Mail. It is unbelievable for me, that years after Apple's cooperation with Microsoft there are still such problems.
I like my Macbooks and I certainly have the absolutely full bandwidth of all Apple products in my household and companies. But I think I have to go back to Microsoft and Sony Laptops in the near future.
Although this kind of bugs are small one's, but the hurt constantly. Apple - please fix that.
Here just for the interested reader is my console error message:
