Hello everyone. 

I need your help. 

We are migrating to Lightning Service Console.

We have an issue with the Email function from Case.

We find that the only way to have the email layout is to create a quick action and have it in the Chatter Published. (in Classic it was a related list)

BUT we have a big issue, when agent wants to send email, always the system set the TO field to the sender of the last email of the case. We can not enforce the Contact email related to the case. Agent must do it manually.

We are back to Classic due to this.

Do you have an idea? what I am doing wrong? 

Thanks
