Hello,
I been beating my head against the wall trying to get this.
scenario: My company want to block all attachments that are sent internally.
Attachments can be sent externally.
now the sticky part
SO, I need to craft a transport rule or rules that would allow internal senders to to send attachments to both internal and external but only if they are addressed to both.
thanks

@Ratpick from your exchange admin center, navigate to Mail flow --- Rules -- Create a new rule and set the following settings as per the screen shot and set the rule to be enforced.
this rule will block any attachments sent internally between the users.
