Hi Keith Caines,
You're right, my bad, sorry.
What you could do, instead of use a policy tip, use "reject the message and include an explanation". See the screenshot below with a test rule with a custom reject message:
You could also create a DLP rule and specify which kind of attachments would you like to block:
Another idea could be to simply reduce the MaxSendSize in your Exchange environment. But that will need a good previous notification to your users or you'll face a huge support request tickets increase.

Hi All,
I am also trying to add a notification tip for all outbound emails with an attachment to external recipients. I want the email to be blocked with an override option for the sender. The purpose is to have the sender review the recipient and attachment for accuracy for DLP and to not send the wrong data to the wrong recipient. This seems to be basic DLP requirements today.
