[horde] [Tickets #14550] Re: Active sync via outlook resulting in memory exhausted

[Porter Rawls]

  For what its worth i have this same issue on one of my email boxes  
with 10880 messages in it.  I;ve tried to increase the php memory in  
the php.ini file, (up to 1GB) but no avail all the memory is consumed.  
 I just have to use the web client to use that mailbox.  It seems (i  
think) that outlooks tries and enumerate all the emails in the mailbox  
before a sync and this causes a out of memory condition on the server.  
 Don't know if this is a "bug" or outlook just being outlook...
