Outlook 2007 font family

I'm using a template which is based on "Template 5 - Left Sidebar" from the resource gallery.

It includes the following CSS:

td.mainbar p {font-family: 'Lucida Grande', Arial, sans-serif;}

However, it looks like Outlook is stripping out all but the first of those fonts. Here's an example of the source when viewed in Outlook 2007. It even adds a 'serif' fall-back!

<p class=MsoNormal style='margin-bottom:9.0pt;text-align:justify'><span
    style='font-size:9.0pt;font-family:"Lucida Grande","serif";color:#666666'>

I've scoured Google but found nothing. Surely this must be a pretty common problem? The simple (but less than ideal) solution would be to put Arial first. However, with this being a CM template, one would expect it to be perfectly coded and cross-client tested?

Thanks in advance for the help!
