++++ Duplicate email items due to broken MOVEITEMS request  
handling.##red|(Worked around as of Horde_ActiveSync 2.16.3)##

  When moving email items from one folder to another, or deleting  
them, Outlook does not follow the specification for handling the move,  
which leads to duplicate email items being present in the destination  
folder. There are two issues interacting here that cause this. The  
first, is that Outlook moves the local item on its own, without  
waiting for the DELETE and ADD commands to be issued from the server.  
Instead, it reassigns the existing email the new UID received in the  
MOVEITEMS response. Secondly, when it receives the ADD command for the  
new email in the destination folder, it fails to treat this command as  
an UPDATE command as the specification says you must when an ADD  
command is received for an already existing UID.
