Sync contacts from Outlook to SOGo with caldavsync

MrH

I installed the application and configured the profile. Everything is detected fine and sync goes well. However no contacts show up in SOGo. Where can I find what goes wrong or where do I find my (so called?) synced contacts?
There are no errors shown also not in the debuglogging…

Dug through the mysql-database and found out that the url had some uppercases in it, where the caldavsyncer did not… Changed it and now it works fine.
