I love my new Nexus 7 (running 4.2.1), but one thing is bugging me and that is when I send an email from my 2 Exchange 2010 Activesync accounts, they're sending as Plain Text. On my HTC Sensation, there is an option in the Activesync settings to choose whether to send as Plain Text or HTML but I cannot find such an option on the Nexus. If I reply to an HTML email sent to me, it replies back as HTML. If I forward an HTML email it sends it correctly as HTML, but composing new messages it always sends as PLain Text.

Server side is OK as from the Sensation (and an iPad) they send as HTML correctly.

Any help greatly appreciated. I will also take being flamed in case it's an obvious thing I've missed but searching various forums has proved fruitless.
