I was trying to clean up my email. First I used the windows live to export all of my folders to a system directory I have for installing and maintenance purposes. I started the process and came back later and it said everything was exported. So I went to the folder I had specified and then to the inbox folder. It had only  exported 4200 out of 34000 files. It had named them some coded name with an eml extension. I checked dates created and noticed that it only created 4 out of 20 for a certain day (Jan 2,2013). It did not included files with attachments. So my question is:

1) why does it only back a portion of the emails in inbox ?

2) why does it not backup  attachements ?
