Shawn,
I appreciate your time and trying to help!
I do not have technical knowledge and can only tell about my own experience and differences between Outlook Express and Windows Live Mail
Windows Live Mail is an online app and therefore every step or action is much, much slower.
Saved drafts disappear or take random time to show up in the draft folder.
Pop-up messages like something failed or did not work due to some connection problems are common (when there were NO connection problems). And the info or your work is lost if you did not copy it just in case.
It's impossible to easily and quickly edit HTML source code in one or two steps!
Moving emails between folders sometimes does not work or takes a long time - it is in fact, unpredictable.
Outlook Express allowed me to shuffle and rearrange folders and messages separately or absolutely independently from online folders.
Windows Live Mail synchronizes all or most actions, it shuffles and rearranges folders and messages the same way in both Windows
Live Mail and in corresponding online folders.
I agree that some ppl would like all these differences or another way of doing things. But some would suffer.
Therefore, my main point is that killing the star (Outlook Express) has hurt many ppl.
and
Giving ppl more choices is better than less!
