>> $conf[activesync][emailsync]=true
>> $conf[activesync][version]=12

Can you try updating to the latest Horde/ActiveSync package and trying  
this now? I think you were hitting up against the sync_cache's data  
field size in the database due to the large (over 3000!) mail folders.  
The sync_cache is only used in EAS 12.1 and above, so that explains  
why this only broke when using the newer version.

There were some other oddities in the log, but they are just poorly  
implemented protocol handling in the client and (hopefully) shouldn't  
cause any problems other than wasted bandwidth.
