Emails are also cached and stored in other computers out in the world. So while you may find Outlook's handling bad, it's nothing compared to outside your PC.
It's hard to find what else you are complaining about. Maybe it's how many PC users refuse to backup what they can't lose. It's their choice. Shouldn't we let them have that choice?
Did you know that even after you empty your "Deleted Items" folder in Outlook.com your e-mails are still kept in a folder called "Recover Deleted Items" ?
It is right there, it is hard not to notice it.
There is the option to "Purge" emails HOWEVER, you can only Purge one at a time AND if you miss click outside the checkbox all the ones you've pre selected will be unchecked and you have to start over
There is NO option to select all.
I had little over 100 messages there. I figured suck it up and get, VERY CAREFULLY, clicking...
Can you imagine folks with 500+ emails ?
Support person from Microsoft Community forums had this to say:
"Unfortunately it is by design in Outlook mail because So many people lost messages through inadvertent deletion."
So people were emptying their "Deleted Items" folder where doing it "inadvertent" ?
This is REALLY bad
I mean, how important is a paper shredder ???
