Microsoft Exchange disclaimer

dionkoffie · March 29, 2018

Hey,

I'm trying to configure exchange so it'll display a warning message when a user in my organization receives an email from someone outside the organization. It all works well, but I'm having a small issue.

As you can see it applies the style to not just the disclaimer, but also the email content itself. How can I remove this?

This is the code I put in the disclaimer:

<html><style>
div {
    background-color: #FFE68A;
    border: 2px solid black;
}
</style>
<div><font color="red">Caution! </font>This is an email from outside the DDL organisation. <br>Do not open the attachment(s) unless you recognize the sender and know the content is safe to open.</div><br><br>
</html>

Configured it like this:

In HTML, just putting text somewhere won't do anything. You need to add a paragraph (I'm not a coder, just something I noticed) using the <p></p> tags within a body segment.

Fixed it. It was a coding issue. Gave the divbox a class and applies the style to that class only. It was applying the style to every div in the email.

I was just in the middle of writing it. Better practice would be to give an id to the div element, because it appears in the message only once. Also make the name of the class/id unique - HTML e-mails might use common element ids/classes like "warning", so try to use something like "warning-outsideDDL" or use inline styling on the div element and then you don't need the style element that affects the whole e-mail.
