AWS tracking does not work with MSO for outlook

I have a rounded button, to make it work in Outlook I have added VML but AWS tracking does not work.

If I put the link inside "" the tracking works, but the button in VML is not clickable.

If I put the link around the VML, the tracking does not work.

Do you know how I can solve it while respecting the code for Outlook?

This is the code:

<tr> <td align="center" class="cta_center" height="50"> <!--[if mso]> <a href="#"> <v:roundrect xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w="urn:schemas-microsoft-com:office:word" href="#" style="height:60px;v-text-anchor:middle;width:250px;" arcsize="50%" strokecolor="#0000ff" fillcolor="#0000ff"> <w:anchorlock/> <center style="color:#ffffff;font-family: Arial, Helvetica, sans-serif;font-size:16px;font-weight:normal;">Enter</center> </v:roundrect> </a> <![endif]-->

<!--[if !mso]><!-->
<a href="#" target="_blank" style="background-color:#0000ff;border:1px solid #0000ff;border-radius:50px;color:#ffffff;display:inline-block;font-family: Arial, Helvetica, sans-serif; font-size:16px;font-weight:normal;line-height:18px;text-align:center;text-decoration:none;width:250px; -webkit-text-size-adjust:none;mso-hide:all; padding: 14px 28px;">Enter</a>
<!--<![endif]-->

</td> </tr>
