Just wanted to share with you a hack to turn on video controls in Outlook.com.

Here you have a nice tutorial about using html5 videos in emails www.emailonacid.com/blog...
The problem is that the control buttons don't appear in Outlook.com if you put
<video width="320" height="160" controls>.
But, after some testing I've found out that if you put <video width="320" height="160" controls=true> it actually works.
Unfortunatly it doesn't work for Outlook.com in Firefox, so if anyone know other ways make it work in Firefox, we'd appreciate it. Cheers.
