Just spent about 2 hours of quality time with the Android SDK emulator  
for Android 6. I had a VERY difficult time getting it to sync at all  
initially until I realized that even though I repeatedly set it up to  
use port 8080 and no ssl, the client would connect ONCE on the correct  
port and load the folder list, then the configuration would revert to  
SSL on port 443 and the account would automatically reset. The only  
way I got it to work was setting up the dev VM I was using with SSL.

Once it started syncing I DID see the same behavior for a few minutes.  
Everything would load, email, contacts, calendar etc... but then the  
client would issue a new FOLDERSYNC with synckey of 0 (which to me  
indicates the internal state for the client was lost/reset).  
Eventually, it stopped doing this and started working normally. No  
change on my part, just let it run for about 15 minutes and it started  
working.

This leads me to believe it is something wrong with the client code,  
and not the Horde ActiveSync code, as there are no errors or no  
incorrect WBXML being sent that I can see.
