Exchange active sync just isn't working

Remote test is working as I should and has done/been.  I have an iPad and android tab that doesn't connect.
But an already configured play book is fine. My android s3 gets to the point where it wants to apply policies.

Memory is also low on my exchange server..

What version of Exchange are you running?

Are you using a 3rd party SSL certificate or self-issued?

David CarrCommented:
ActiveSync is different for all platforms including  iOS and Android. Are you using the same ActiveSync Policyt for all devices? Are you getting errors? Do you have anything between Exchange and the devices like ISA or TMG or F5?
Exchange 2010 is designed to use up as much memory as needed.  It will reassign it if it is needed elsewhere.  How much memory do you have?  Are all roles contained in 1 server?  How many users?

Also got this from exchange regards my android:

Your phone won't be able to synchronize with the server via Exchange ActiveSync because of an access policy defined on the server.

Odd, the EMC shows first sync time and last policy update time of 17:42
But in my OWA it shows:
First sync:      27/08/2013 18:42
Last successful sync:      27/08/2013 19:10

Seems like this was related to a vmware/acronis snapshot issue we recently had.  Very odd things happening, but all ok now..
