css - display:none doesn't work on Outlook 2007

Question

I want to send an e-mail from our system to customers, where some tags should be hidden to them. I've set the following CSS:

.hidden { display: none; }

But this does not work. What solutions or alternatives are there for hiding elements in an e-mail?

Answer 1

Use mso-hide:all in a span surrounding the content, and on any other tags within the span.
