CSV-input: converting specific field(s) to lowercase

Dear community,

I'm currently working on parsing MS Exchange logs and sending them via GELF to my graylog instance.

I'd like to convert the sender- and recipient-address field to lowercase. Sounds pretty easy, in fact, I need help :(

my current config looks like this (below). Any help is appreciated.

I've tried to work with "Exec       $sender-address = lc($sender-address);" within the input as well as Output backet - neither did work.
