Bump - Anybody any idea where to start? Is this a closed source component with no user setting possible, where I have to wait for a bug fix by Nokia / Microsoft, which will not come?

Any alternative solution?

The problem is, even when I change a date on ToDo list entry only using the phone, the whole ToDo note is messed up in my Microsoft Exchange account. By the way, that happens also, if I am using syncevolution, Nokia Suite, CalDav or Buteo.
