Is there a way to change the "Ticket" in Re: [Ticket#...] in the subject of the outgoing emails to desired language? For example -> Re: [Ärende#...] And how would this affect the system?

See http://doc.otrs.org/2.0/en/html/x7930.html#Ticket:Core::Ticket You have to set/change $Self->{Ticket::Hook} in /opt/otrs/Kernel/ Config.pm. I have the default in there: $Self->{Ticket::Hook} = 'Ticket#'; But you could change it to: $Self->{Ticket::Hook} = 'Ärende#'; Nils Breunese.
