Perhaps sogo thinks, that this phone already did get those emails. In order to rule that out, you would have to purge all ActiveSync informations for that client and start a new sync. What are your settings in sogo.conf for SOGoMaximumPingInterval SOGoMaximumSyncInterval SOGoInternalSyncInterval SOGoMaximumSyncWindowSize SOGoMaximumSyncResponseSize WOWatchDogRequestTimeout SxVMemLimit Which timeout is set in the ProxyPass directive in your apache configuration for the ActiveSync part? I suspect, that the synchronization is interrupted either by apache or by the watchdog. Or you have set up a very slow synchronisation, which will take ages to complete. > 3.

As that works, no problem here either. Kind regards, Christian Mack > On 2/18/2016 5:36 PM, John Underwood wrote: >> Thanks for the information.
