Hamburger Menu Stopped Working in Office 365 and Outlook.com
I've been using Jerry Martinez technique for a little while now (full article here http://bit.ly/1MxcBRt) and have just noticed that this has started breaking in Outlook 365 and Outlook.com. Basically the whole top module section isn't displayed (see https://litmus.com/pub/d26f56a)
As far as i can tell it's to do with the display:none/Visibility:none/Overflow:none styles on either the input or the mso conditional p tags.
Any help on getting this to work would be greatly apprciated.
