Eloqua Dynamic Content is not working on Outlook when using inside MSO code

Question

On Eloqua, I have tried to put a dynamic content inside MSO code for outlook. But that dynamic content block is not showing on outlook platform.

This is working on Gmail and other platforms.

Only not working on outlook (<!--[if mso]>)

Code:

<!--[if mso]>
<span elqid="12345" elqtype="DynamicContent" class="remove-absolute" style="display: block"></span>
<![endif]-->  
                                          
<!--[if !mso]> -->
<span elqid="12345" elqtype="DynamicContent" class="remove-absolute" style="display: block"></span>
<!-- <![endif]-->
