Can't change resolution message

Can't change resolution message

Hello!

Our team is in the process of testing Zoho desk. So far, I have successfully changed several of the notifcation messages sent to customers (new ticket / confirmation of a ticket answer / ticket closed). However, what I can't find is a way to change the resolution message. By standard, this one goes "dear xy; abc has provided the following resolution to the ticket [...]".

How do I change it? It's not in the "Notfication Rules" Settings. 

Thanks a lot!

Best,

Reinhard
