"The problem lies with self signed certificates or CA certificates approved without an android.
The button accept all certificates does not operate well
The system can not add a CA unless you have a P12 certificate. And even the certificate not allways properly install.
There are three simple solutions:
1. Install and manage touchdown exchange mails and contacts from it. (demo 30 days)
2. Install a certificate from a recognized company like Verisign startssl (free) or another.
3. Wait for the final OTA and meanwhile see yours mails from OWA normally

Makes no sense to go round in circles, try a solution and claim directly to google for the publication of a new ota arranging.
From my point of view perhaps the best and safest is to change the certificate by one of a CA recognized.
Finally if your problem is " This server requires security features your phone does not support " you have two solutions
Add an exception to your user in Exchange Admin
Wait for de OTA with this feature released.
I hope this finally clarifies yours doubts.
Thanks all
