Dear Dirk,

Thank you very much. It is all fine now again. It just installed app-kopano-basic and app-kopano-basic-core.

My subscription is also shown in the webconfig again (I do not have the community version). The reason for the "test-server" version was an update to kopano 8.5.8 posted by Ben if I remember correctly (link). It could not be done over the normal updates, because it needed some hands on and is still just available over the "test-server" version. The reason why I wanted the webconfig setup back is that I like the recursive backup method built in kopano, which is easier to access through the webconfig. I additionally backup the database and attachments on a daily base for disaster recovery.

Thank you again. You helped me a lot.

Best wishes,

Robert
