Ok. So the main issue now is that some devices do not support cookies,  
and when cookies are unavailable, our Auth code tries to use the  
session_id as the secret key. I don't think the proper fix for this is  
to enable sessions for AS requests though, as that would incur a lot  
of overhead considering how many and how frequent the AS requests  
could be. There is no other session storage requirement from AS's  
point of view. I think we need to figure out another key to use in the  
circumstances, if this is possible.

These are all normal and expected responses. Devices can limit the  
number of contacts ("messages" in AS speak), that are allowed to be  
sent in a single session. Horde keeps track of the messages that have  
yet to be sent and sends them during the subsequent SYNC requests. You  
can verify that *this* part is at least working by looking at the  
horde_activesync_state table, in the 'data' field. That should contain  
the data for the 'missing' contacts.

It could be that a php error has made it to the wbxml stream, or that  
the device doesn't properly support the 'moreavailable' tag or..? I  
would check the server error log for any errors - and a network trace  
in this case would probably be helpful.
