I have set the Tracking token settings as below:
Prefix : CRM
Deployment base tracking number : 0
Number of digits for user numbers : 3
Number of digits for incremental message counter : 9
Tracking token preview CRM:0001000000001
but CRM is generating (CRM:0000000000000001) for different emails related to different Cases, when any contact is replying on top of those emails then they are getting attached to wrong Cases.
how to fix this issue.
