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

    To me it looks like you may have two Mail Flow rules, or one rule with two actions. 

       One that is Prepending the disclaimer (Yellow one that starts with "Caution")

       And one that is Appending the disclaimer (Red one that starts with "[External")

    I can't seem to remove the image that comes at the bottom! Can you help?

    I have used the exact HTMP that you have provided in the article.
