We know Outlook doesn't support display:none. I've read if you wrap your mobile content with <!--[if !mso]><!--> and a DIV and a table with style="display: none; font-size: 0; max-height: 0; line-height: 0; padding: 0; mso-hide: all;" this should hide mobile code. It does for Desktop Clients and outlook.com, but not OWA. OWA is greatly used for businesses and organizations, I was surprised Litmus doesn't test OWA.

Does anyone have any possible solutions to hide mobile content within OWA?
