Footer text disappears in Outlook/Windows email testing - html

Question

Not sure why this is happening. The footer text completely disappears in Outlook/Windows email testing. All other email clients work and, the footer appears, as it should.
Here is the template with the footer code. Did I miss closing a table or? Any suggestions? So odd-thanks for looking.
```
`<table role="presentation" width="100%" cellpadding="0" cellspacing="0" border="0">
<tr>
<td align="center" class="darkmode-footer" bgcolor="#122147" style="padding: 50px 15px;">
<table role="presentation" class="w100p" cellpadding="0" cellspacing="0" border="0" style="width: 600px; max-width: 600px;">
<tr>
<td align="center"><a href="" target="_blank"><!--[if !mso]><! -->
<div style="text-align: center;">
<br>
<span style="font-size:10px;"><span style="color:#ffffff;">You are receiving this email because you are a valued friend of the .<br>

Answer 1

If you put the code which you posted into a snippet here (as I did) and in the editor click "Tidy" to properly format it, you will notice a non-fitting </td>in the 9th-to-last line, and also these superfluous closing tags in the last three lines:
</td>
</tr>
</table>
The snippet's browser emulator obviously is tolerant in fixing these errors, but I can imagine that especially mail applications like Outlook won't be that tolerant and treat this in another way.

You have a stray <!--[if !mso]><! -->, without a closing if (endif).
Remove that, and the text will show.
