Exchange Hybrid Rule Block Files

I have a 2016 / 365 Hybrid Deployment

I have a Rule that blocks EXE Files

When a user sends an EXE the file is blocked and the Reply to address is from someone who no longer works at the company.

I can not fin anywhere to change this.

What does the rule look like? Usually, this is handled by the default Exchange recipient object, you can change it as detailed here: https://docs.microsoft.com/en-us/exchange/mail-flow/non-delivery-reports-and-bounce-messages/ndr-pro...
