Mail Flow - External Message Warning HELP

Anonymous

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>

Microsoft 365 and Office | Subscription, account, billing | For home | Windows

Hi BH33,

Thanks for provide the details in your post. About your question, please kindly check following steps to see if it can help you fix this issue:

  1. In Exchange Admin Center, go to mail flow > rules and then click "+" to create a new rule.
  2. Then set the new rule like below picture:

Note: in step 4, please enter following code: 

<p><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></p>

I have tested above rule on my side and I can successfully show the warning message(see below picture), if you have any problems when doing so, please feel free to post back and provide us a screenshoot of the detailed information about the rule you created for analysis.

Regards,

Jennifer

    Going a step forward, could be great if there's an option of include received Plain Text emails or another way round: convert any incoming Plain Text email to HTML.

    Is it that possible?

    Thanks,

    This worked great for me. but when a message comes in it duplicates the Banner.  I cut and pasted the txt from above.  Any comments.

    ASGAU, 

    This is HTML code. At the end of your banner add a line break or however many you need.

    A line break is just <br>
