Worknotes still being created from emails after deactivating Email Inbound Actions

[Nimeku]

We have deactivated all Email Inbound Actions/Flows for INC in our ServiceNow instance, but when we send emails with incident numbers in the subject line (e.g., "re: INC123456789"), worknotes are still being automatically added to the incidents. Is this a core functionality? What other email processing mechanisms in ServiceNow could be handling this beyond Email Inbound Actions/Flows? Where should we look to identify what's processing these emails? How can we completely disable automatic worknote creation from emails (we want to control this via Inbound Email Actions)?

Thank you for the reply. This is not about the Outbound Notifications, but rather the Inbound Email Handling. 

When we send an Email to the ServiceNow Instance with a specific subject (re: INCXXXXXX), the system puts the Email to the Activitiy Stream of that repective Incident mentioned in the subject. 

Although we have disabled all Inbound Email Actions, we still see the Entry in the Activity Stream, when we send an Email to the ServiceNow Instance.

@Nimeku then please inspect who is the notification sender and if it is not desired behaviour, deactivate that user (unless it is guest)..

@Nimeku

share screenshots.

Did you check the incoming email and see in related list?

It will tell which inbound email action was processed for that email record.
