Outlook 2013/2010 nightmare #2

Yes Eric,

Outlook also has a declaration that as of either version 2010 or 2013, 
they no longer download IMAP headers, they download the whole message - 
thank God for faster Internet connections these days - could you imagine 
that in the older dialup days? Still it is a waste of bandwidth and disk 
space to do this.

I am so tired of how they claim to use the RFC and indicate they are 
'compatible' with a certain protocol/procedure, but really just move the 
goal posts so you can only talk to M$ stuff at the back end using their 
enforcements.

All part of locking people into the "perpetual upgrade" path I guess.
