Padding Fix in Outlook 2007

I'm having custom buttons attachted to an <a> tag.


.primarybutton a{color: #FFFFFF; 
margin: 0; 
padding: 5px 10px;  
background: #5E82AB url(img/primary-glow.jpg) no-repeat left top; 
font-size: 14px; 
width: auto; 
line-height: 27px;}


<p class="primary-button"><$title link='true' default='Read more'$></p>

As usual the background isn't working in Outlook 2007, but hey I have a fallback color, so that's ok.
The only thing is that I need the padding. Does anyone knows a fix on this.

Most of the time I solve this width blank.gif images, but not possible in this case cause it's an editable item.
