There is an issue that is well described in this post (https://discussions.apple.com/thread/5817893?tstart=0) where notes edited on iOS 7 device do not show in Outlook properly (you can see them but they are blank), however they show in OWA just fine (Exchange 2013 SP1 with Outlook 2010 and 2013).
This appears to be a MS issue (since EAS syncs them and info displays in OWA), if so when will MS be fixing the bug?
