I would like the system automatically to create a new case when email subject changes. I found the MS official documentation, but it has been confirmed that Power Automate cannot be implemented in On-premises environment.

Current CRM Setup:

Version: D365 v9 On-Premises

Email Settings:

a) Use folder-level tracking for Exchange folders (server-side synchronization must be enabled): No

b) Use correlation to track email conversations: Yes

c) Use smart matching: No

d) Track emails sent between Dynamics 365 users as two activities: Yes

e) Auto case creation rule: Refer to attached file for reference (if needed)

Please help me find a workaround for this scenario.
