Question about Outlook Express

My elderly mother crashed her e-mail somehow.  She has Comcast as a provider, and there is Live Mail icon on her desktop, which she would click and her mail would come up.  Anything beyond clicking the icon is too complicated for her (i.e. going into Comcast online and signing in, which does indeed work bypassing Live Mail).  So I have to get the Mail to work from the desktop icon.

After this crash you click the icon and the Mail comes up and there is nothing in any of the folders, and all folders (inbox, sent, etc)  There is a thin black bar at the top of the page and below is a message "Unable to display folder".

Does anyone know what I may do to fix this.  I tried uninstalling Live Mail and re-installing but when I did that it restored to her old e-mail and I get the same error message.

Thanks for any help

Original title: Windows Live Mail - Quick Views issue

Note: This question has appeared before but with no clear and concise answer to the question.  I have emails appearing in Windows Live Mail (2012) Quick Views but they can not be accessed, deleted, or even found by the system and yet they are clearly visible in this view.  I went so far as to re-install windows live essentials but to no avail.  Can anyone suggest a proven method to rectify this issue?

I check my e-mails everyday on Windows Live but I am getting overleoaded with Spam & unread feeds.

I don't know why but I now received multiple e-mails from companies ,e.g  NHS etc.

How do I stop this rubbish as my trash bin daily goes up t 150+ e-mails to be deleted.
