Howdy email-o-reenos!

Anyone have a fix for tight line-height spacing in Outlook 07, 10, 13 and outlook.com? I've been searching for an answer on the interwebs but everyone seems to experience the opposite, with overly spacious line-height displaying in the mentioned Outlook culprits.

I've included the following code in my embedded styles but have seen no improvement. Your expertise is greatly appreciated! Thank you!

.ExternalClass * {
line-height: 100%;
}
