Block outbound NTLM auth

With CVE-2018-0950 from Microsoft, if an outlook user clicks on an OLE object in an RTF email, the client will send credentials try to logon. Our security group is quite concerned about this.

 

While allowing ports 445, 137 and 139 out to the internet is a really bad idea, they want to make sure that it is explicitly blocked. Is the application "ms-netlogon" the app to block? It includes many more ports than just the three mentioned above. Is anyone else doing this? Are 'we' just overreacting?
