Hi Mike,

After the recent updates with fixed horde_smtp, there is still the  
problem with ActiveSync on iOS (empty message bodies, not attachments  
being displayed) and Outlook. In the sync log I see several error  
messages (Outlook):

2014-11-23T20:30:58+01:00 ERR: [19950] Attempting to add a collection
                     to the sync cache while requiring a synckey, but no
                     synckey could be found. Most likely a client error in
                     requesting a collection during PING before it has issued a
                     SYNC.

2014-11-23T20:30:58+01:00 ERR: [21584]  
Horde_ActiveSync_Collections::getBackendIdForFolderUid failed because  
folder was not found in cache.
