I know this isn't a new problem but I've tried fixing it. I was tasked with creating this email by a new client and although it works in a browser, some versions of Outlook, Mail, Outlook.com, iPhone, the layout breaks in Outlook 07/10.

I believe this is down to Outlook adding borders to tables/table cells and I've tried working around this but if I make the tables narrower, then it doesn't look right in other clients. I tried the email on acid aolution of adding a border but couldn't get that to work.

Here's a link to the email/code:

Any ideas or tips would be amazing.
