Hi All

We have enabled Email-to-case settings and created Queues so that each case is assigned to Queues. Each Queue has email IDs. So when user emails to one of the Salesforce email address a new case is created and I have created a process builder to send automatic reply on Case creation with FROM Email Address as that of same Queue email address.

But now I am facing issue when customer replies on that automatic email. Its creating a new case. I have included Case.Thread_id in email template but its not working.

Can you please provide a solution for same.
