Creation & Update rules ignored if assigning to queue

Hi there,

I don't know if I have an issue with my C&U rule for my queue or if I try a wrong approach, because I cannot set "queue item" as source for my rules.

What I'm trying to do: I have an email in queue A and assign it to queue B. Because of it's still an email I thought the C&U rule would work, but it seems totally ignored (not triggered).

What am I doing wrong?

Thanks for any advice

Tom
