Outlook Conditional Not Applying to 2007 and 2010

Hi Guys

We're using:

h2 {
        font-size: 39px;
        line-height: 40px;
        color: #ffffff;
        font-weight: normal;
        margin: 0;

<!--[if gte mso 12]>
h2 {
        font-size: 37px !important;
        line-height: 37px !important;
        color: #ffffff !important;
        font-weight: normal !important;

And for what ever reason Outlook is not applying these conditional styles. Does anyone have any other tricks that we might want to try?

Heres a little something I discovered that I haven't seen anywhere else

<!--[if (mso)|(IE)]>

This covers any Outlook, whether it's mso (2007, 2010, 2013) or ie (2003).

Could it be that the cause of your problem is that you're using odd values for line-height and font-size? I remember that outlook only supports even values for font-size and line-height.
