Again some tests with Outlook and ActiveSync. It's still not working  
like prior to ActiveSync 2.20.*. The full collection never gets  
synced, Outlook retrieves identical ServerEntryIDs multiple times, but  
in the client no email appears. When I sync only the last month, some  
utems got synced, before the syncing process stops. The Log says, that  
it found loads of changes, but they don't get synced. Any progress  
here? OL sync was working almost perfectly in the last weeks. Anyone  
else witnessing this? (in case you have an up-to-date horde  
installation)
