Mail Flow - External Message Warning HELP

Hello!

I'm trying to setup a mail flow rule for external email messages from non-organization addresses. I have it setup great, however I have it coded so that it displays the yellow background, red boarder etc and it displays perfect in a sample code viewer. However, when I add it to my rule and then send a test message to my email from outside the org, it doesn't display any of these colors. HELP?? I have included my code below. I'm using 0365

<div style="background-color:#FFEB9C; width:100%; border-style: solid; border-color:#9C6500; border-width:1pt; padding:2pt; font-size:10pt; line-height:12pt; font-family:'Calibri'; color:Black; text-align: left;"><span style="color:#9C6500"; font-weight:bold;>CAUTION:</span> This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe.</div><br>

1. In Exchange Admin Center, go to mail flow > rules and then click "+" to create a new rule.

Note: in step 4, please enter following code:
