Hi and thanks again for your thoughfull answer.
As you can see I have all the notification enabled, but if any agent add a note to a ticket assigned to a differnet agent, nothing is sent out.
The same thing happens if I as an Agent create a ticket to another agent. The other agent answer the ticket, i DO get a reply. But if i then update the ticket back, no mail is sent to the agent i assigned for it.
I have never seens a mail missing when a client create ticket and agent reply. We can go back and forward and it all works as it should.
I also have this issue on an older version of Osticket we use on a different system, so there we just got used to send a manual mail with link to update when this happened to alert the agent.
I am sorry i am not a real coding guy so its a little hard to trouble shoot code for me, but i am struggeling to trouble shoot this.
The tickets we add notes to are NOT closed but Open
