Summary of the issue you are facing:
Some Users synchronise their calender in outlook with the CalDav Synchronizer Add-In.
Only one user get the error message “Unknown or bad timezone (Europe/Kiev)”. But we are in timezone “Europe/Berlin”. The Windows timezone is also ok.
I check the timezone for this user in the web calender. It was set to automatic “Europe/Berlin”. I set it fix to “Europe/Berlin”. I checked this also with the command “occ user:setting user1234”. Both entries in core and calendar are set to “Europe/Berlin” also in outlook.
