Yes, I also think that something went wrong during the update to the 
latest patchlevel of horde 3.x, but the question is what :-(. There were 
so many changes to the database for this old versions of horde and its 
applications :-(. How can I find out if I am at the latest patchlevel 
for horde 3.x and every application I use?

How can this be done?

The only important data I have to migrate are the addresses, for all 
other userspecific data starting from scratch is OK or even the better 
solution.
