I have merged your post with your original thread.
Please continue replies for this issue in this thread.
Did you locate an archive.pst file, if so, did you connect the archive.pst file to Outlook to view the contents?
How many e-mail accounts do you have set up in Outlook?
Do you have all of them configured to: Leave a copy of messages on the server?
I have not heard of that setting failing.
Try creating a new profile in Outlook 2007 and use the new profile for a week, or so, to see if the same issues occur:
How to create a new e-mail profile in Outlook 2007 and in Outlook 2003

File > Open > Outlook Data File Browse to the location of the .pst file and select it, the Personal Folders should appear in the new Outlook profile.
