Is there an auto save feature in Live Mail like the one in Hotmail

My mother bought a new computer (running Windows 7 Professional) and her two email clients both import and are read and write

accessible from a "master" Windows Live Mail window.

Every once in a while, she will be typing an email and it will simply disappear, causing her to retype the entire thing. I think it has

something to do with accidentally hitting a hotkey. But...that's a different question.

To preface my real question:

I use Hotmail in which is incorporated a feature which automatically backs up an email in progress, at short intervals, and places said email

into a "Drafts" folder. This way, if an email ever "disappears"  prior to being sent,  I can merely login to "Drafts" and most of what I had been

composing typing remains accessible.

Here is the question:

I can't find a link to a similar function on my mother's Windows 7 Professional Live Mail. Does one exist? If so, is there a setup sequence

I can access in order to enable the appearance of a "Saved Drafts" option on the Live Mail email window?

Thanks
